Sinn Féin

Sinn Féin (/ʃɪn ˈfn/ shin FAYN,[6] Irish: [ʃɪnʲ ˈfʲeːnʲ]; English: "[We] Ourselves")[7] is an Irish republican[1] and democratic socialist[1] political party active in both the Republic of Ireland and Northern Ireland.

The original Sinn Féin organisation was founded in 1905 by Arthur Griffith, but has split substantially on a number of occasions since then, notably giving rise in the aftermath of the Irish Civil War to the two traditionally dominant parties of southern Irish politics: Fianna Fáil, and Cumann na nGaedheal (now Fine Gael).

The contemporary Sinn Féin party took its form in 1970 after another split (with the other faction eventually becoming the Workers' Party of Ireland) and was historically associated with the Provisional Irish Republican Army (IRA).[8] Mary Lou McDonald became party president in February 2018.

Sinn Féin is one of the two largest parties in the Northern Ireland Assembly, winning one seat less than the Democratic Unionist Party (DUP) at the 2017 Northern Ireland Assembly election. In that assembly it is the largest Irish nationalist party, and it holds four ministerial posts in the power-sharing Northern Ireland Executive as of 2020. In the UK House of Commons, Sinn Féin holds seven of Northern Ireland's 18 seats, making it the second-largest bloc after the DUP; there it follows a policy of abstentionism, refusing to sit in parliament or vote on bills. In the Oireachtas (the lower house and upper house of the Republic of Ireland), it is the third largest party. However in Dáil Éireann Sinn Féin currently sits as the main opposition and the second largest party having won the largest share of first-preference votes at the 2020 Irish general election.


The phrase "Sinn Féin" is Irish for "Ourselves" or "We Ourselves",[9][10] although it is frequently mistranslated as "ourselves alone" (from "Sinn Féin Amháin", an early-20th-century slogan).[11] The name is an assertion of Irish national sovereignty and self-determination; i.e., the Irish people governing themselves, rather than being part of a political union with Great Britain under the Westminster Parliament.

A split in January 1970, mirroring a split in the IRA, led to the emergence of two groups calling themselves Sinn Féin. One, under the continued leadership of Tomás Mac Giolla, became known as "Sinn Féin (Gardiner Place)", or "Official Sinn Féin"; the other, led by Ruairí Ó Brádaigh, became known as "Sinn Féin (Kevin Street)", or "Provisional Sinn Féin". As the "Officials" dropped all mention of Sinn Féin from their name in 1982–instead calling themselves the Workers' Party of Ireland–the term "Provisional Sinn Féin" has fallen out of use, and the party is now known simply as "Sinn Féin".

Sinn Féin members have been referred to colloquially as "Shinners", a term intended as a pejorative.[12][13]



Arthur Griffith

Sinn Féin was founded on 28 November 1905, when, at the first annual Convention of the National Council, Arthur Griffith outlined the Sinn Féin policy, "to establish in Ireland's capital a national legislature endowed with the moral authority of the Irish nation".[10][14] Its initial political platform was both conservative and monarchist, advocating for an Anglo-Irish dual monarchy unified with the British Crown (inspired by the Austro-Hungarian Compromise of 1867).[15] The party contested the 1908 North Leitrim by-election, where it secured 27% of the vote.[16] Thereafter, both support and membership fell. At the 1910 Ard Fheis (party conference) the attendance was poor, and there was difficulty finding members willing to take seats on the executive.[17]

The campaign car of Joseph McGuinness, who won the 1917 South Longford by-election whilst imprisoned. He was one of the first Sinn Féin members to be elected. In 1921 he sided with Collins in the Treaty debate.

In 1914, Sinn Féin members, including Griffith, joined the anti-Redmond Irish Volunteers, which was referred to by Redmondites and others as the "Sinn Féin Volunteers". Although Griffith himself did not take part in the Easter Rising of 1916, many Sinn Féin members did, as they were also members of both the Volunteers and the Irish Republican Brotherhood. Government and newspapers dubbed the Rising "the Sinn Féin Rising".[18] After the Rising, republicans came together under the banner of Sinn Féin, and at the 1917 Ard Fheis the party committed itself for the first time to the establishment of an Irish Republic. In the 1918 general election, Sinn Féin won 73 of Ireland's 105 seats, and in January 1919, its MPs assembled in Dublin and proclaimed themselves Dáil Éireann, the parliament of Ireland. The party supported the Irish Republican Army during the War of Independence, and members of the Dáil government negotiated the Anglo-Irish Treaty with the British government in 1921. In the Dáil debates that followed, the party divided on the Treaty. The pro-Treaty and anti-Treaty components (led by Michael Collins and Éamon de Valera respectively) managed to agree on a "Coalition Panel" of Sinn Féin candidates to stand in the 1922 general election.[19] In the wake of the vote, anti-Treaty members walked out of the Dáil, and pro- and anti-Treaty members took opposite sides in the ensuing Civil War.[20]


Pro-Treaty Dáil deputies and other Treaty supporters formed a new party, Cumann na nGaedheal, on 27 April 1923 at a meeting in Dublin, where delegates agreed on a constitution and political programme.[21] Cumann na nGaedheal went on to govern the new Irish Free State for nine years. (It merged with two other organisations to form Fine Gael in 1933.)[22] Anti-Treaty Sinn Féin members continued to boycott the Dáil. At a special Ard Fheis in March 1926, de Valera proposed that elected members be allowed to take their seats in the Dáil if and when the controversial Oath of Allegiance was removed. When his motion was defeated, de Valera resigned from Sinn Féin; on 16 May 1926, he founded his own party, Fianna Fáil, which was dedicated to republicanising the Free State from within its political structures. He took most Sinn Féin Teachtaí Dála (TDs) with him.[23] De Valera's resignation meant also the loss of financial support from America.[24] The rump Sinn Féin party could field no more than fifteen candidates,[25] and won only six seats in the June 1927 general election, a level of support not seen since before 1916.[26][27] Vice-President and de facto leader Mary MacSwiney announced that the party simply did not have the funds to contest the second election called that year, declaring "no true Irish citizen can vote for any of the other parties".[27] Fianna Fáil came to power at the 1932 general election (to begin what would be an unbroken 16-year spell in government) and went on to long dominate politics in the independent Irish state.

An attempt in the 1940s to access funds that had been put in the care of the High Court led to the Sinn Féin Funds case, which the party lost and in which the judge ruled that it was not the legal successor to the Sinn Féin of 1917.[28] At the 1955 United Kingdom general election, two Sinn Féin candidates were elected to Westminster, but the party's vote decreased at the following election in 1959, during the IRA's Border Campaign.[29] Through the 1960s, some leading figures in the movement, such as Cathal Goulding, Seán Garland, Billy McMillen, Tomás Mac Giolla, moved steadily to the left, even to Marxism, as a result of their own reading and thinking and contacts with the Irish and international left. This angered more traditional republicans, who wanted to stick to the national question and armed struggle.[30] The Garland Commission was set up in 1967, to investigate the possibility of ending abstentionism. Its report angered the already disaffected traditional republican element within the party, notably Seán Mac Stíofáin and Ruairí Ó Brádaigh, who viewed such a policy as treason against the Irish Republic.[31]


2 Kevin Street, Dublin, location of Provisional Sinn Féin's first head office.
Ruairí Ó Brádaigh was the president of Provisional Sinn Féin from 1970 until 1983.

The Sinn Féin party split in two at the beginning of 1970. On 11 January, the proposal to end abstentionism and take seats, if elected, in the Dáil, the Parliament of Northern Ireland and the Parliament of the United Kingdom was put before the members at the party's Ard Fheis.[32] A similar motion had been adopted at an IRA convention the previous month, leading to the formation of a Provisional Army Council by Mac Stíofáin and other members opposed to the leadership. When the motion was put to the Ard Fheis, it failed to achieve the necessary two-thirds majority. The Executive attempted to circumvent this by introducing a motion in support of IRA policy, at which point the dissenting delegates walked out of the meeting.[33] These members reconvened at Kevin Barry Hall in Parnell Square, where they appointed a Caretaker Executive with Ruairí Ó Brádaigh as chairman.[34] The Caretaker Executive's first act was to pass a resolution pledging allegiance to the 32-county Irish Republic and the Provisional Army Council.[35] It also declared itself opposed to the ending of abstentionism, the drift towards "extreme forms of socialism", the failure of the leadership to defend the nationalist people of Belfast during the 1969 Northern Ireland riots, and the expulsion of traditional republicans by the leadership during the 1960s.[36]

At its October 1970 Ard Fheis, delegates were informed that an IRA convention had been held and had regularised its structure, bringing to an end the 'provisional' period.[37] By then, however, the label "Provisional" or "Provo" was already being applied to them by the media.[38] The opposing, anti-abstentionist party became known as "Official Sinn Féin".[39] It changed its name in 1977 to "Sinn Féin – The Workers' Party",[30] and in 1982 to "The Workers' Party".[40]

Because the "Provisionals" were committed to military rather than political action, Sinn Féin's initial membership was largely confined, in Danny Morrison's words, to men "over military age or women".[41] A Sinn Féin organiser of the time in Belfast described the party's role as "agitation and publicity".[41] New cumainn (branches) were established in Belfast, and a new newspaper, Republican News, was published.[42] Sinn Féin took off as a protest movement after the introduction of internment in August 1971, organising marches and pickets.[43] The party launched its platform, Éire Nua ("a New Ireland") at the 1971 Ard Fheis.[44] In general, however, the party lacked a distinct political philosophy. In the words of Brian Feeney, "Ó Brádaigh would use Sinn Féin ard fheiseanna (party conferences) to announce republican policy, which was, in effect, IRA policy, namely that Britain should leave the North or the 'war' would continue".[45] Sinn Féin was given a concrete presence in the community when the IRA declared a ceasefire in 1975. 'Incident centres' were set up to communicate potential confrontations to the British authorities. They were manned by Sinn Féin, which had been legalised the previous year by Merlyn Rees, Secretary of State for Northern Ireland.[46]

Political status for prisoners became an issue after the ending of the truce. Rees released the last of the internees, and ended 'Special Category Status' for all prisoners convicted after 1 March 1976. This led first to the blanket protest, and then to the dirty protest.[47] Around the same time, Gerry Adams began writing for Republican News, calling for Sinn Féin to become more involved politically.[48] Over the next few years, Adams and those aligned with him would extend their influence throughout the republican movement and slowly marginalise Ó Brádaigh, part of a general trend of power in both Sinn Féin and the IRA shifting north.[49] In particular, Ó Brádaigh's part in the 1975 IRA ceasefire had damaged his reputation in the eyes of northern republicans.[50]

The prisoners' protest climaxed with the 1981 hunger strike, during which striker Bobby Sands was elected Member of Parliament for Fermanagh and South Tyrone as an Anti H-Block candidate. After his death on hunger strike, his seat was held, with an increased vote, by his election agent, Owen Carron. Two other Anti H-Block candidates were elected to Dáil Éireann in the general election in the Republic. These successes convinced republicans that they should contest every election.[51] Danny Morrison expressed the mood at the 1981 Ard Fheis when he said:

Who here really believes we can win the war through the ballot box? But will anyone here object if, with a ballot paper in this hand and an Armalite in the other, we take power in Ireland?[52]

This was the origin of what became known as the Armalite and ballot box strategy. Éire Nua was dropped in 1982, and the following year Ó Brádaigh stepped down as president, and was replaced by Adams.[53]


Under the political leadership of Gerry Adams and Martin McGuinness, Provisional Sinn Féin adopted a reformist policy, eventually leading to the Good Friday Agreement.

Under Adams' leadership electoral politics became increasingly important. In 1983 Alex Maskey was elected to Belfast City Council, the first Sinn Féin member to sit on that body.[54] Sinn Féin polled over 100,000 votes in the Westminster elections that year, and Adams won the West Belfast seat that had been held by the Social Democratic and Labour Party (SDLP).[54] By 1985 it had fifty-nine seats on seventeen of the twenty-six Northern Ireland councils, including seven on Belfast City Council.[55]

The party began a reappraisal of the policy of abstention from the Dáil. At the 1983 Ard Fheis the constitution was amended to remove the ban on the discussion of abstentionism to allow Sinn Féin to run a candidate in the forthcoming European elections. However, in his address, Adams said, "We are an abstentionist party. It is not my intention to advocate change in this situation."[56] A motion to permit entry into the Dáil was allowed at the 1985 Ard Fheis, but did not have the active support of the leadership, and it failed narrowly.[57] By October of the following year an IRA Convention had indicated its support for elected Sinn Féin TDs taking their seats. Thus, when the motion to end abstention was put to the Ard Fheis on 1 November 1986, it was clear that there would not be a split in the IRA as there had been in 1970.[58] The motion was passed with a two-thirds majority. Ó Brádaigh and about twenty other delegates walked out, and met in a Dublin hotel with hundreds of supporters to re-organise as Republican Sinn Féin.[59]

Tentative negotiations between Sinn Féin and the British government led to more substantive discussions with the SDLP in the 1990s. Multi-party negotiations began in 1994 in Northern Ireland, without Sinn Féin. The Provisional IRA declared a ceasefire in August 1994. Sinn Féin then joined the talks, but the Conservative government under John Major soon came to depend on unionist votes to remain in power. It suspended Sinn Féin from the talks, and began to insist that the IRA decommission all of their weapons before Sinn Féin be re-admitted to the talks; this led to the IRA calling off its ceasefire. The new Labour government of Tony Blair was not reliant on unionist votes and re-admitted Sinn Féin, leading to another, permanent, ceasefire.[60]

The talks led to the Good Friday Agreement of 10 April 1998, which set up an inclusive devolved government in Northern Ireland, and altered the Dublin government's constitutional claim to the whole island in Articles 2 and 3 of the Constitution of Ireland. Republicans opposed to the direction taken by Sinn Féin in the peace process formed the 32 County Sovereignty Movement in the late 1990s.[61]


The party expelled Denis Donaldson, a party official, in December 2005, with him stating publicly that he had been in the employ of the British government as an agent since the 1980s. Donaldson told reporters that the British security agencies who employed him were behind the collapse of the Assembly and set up Sinn Féin to take the blame for it, a claim disputed by the British government.[62] Donaldson was found fatally shot in his home in County Donegal on 4 April 2006, and a murder inquiry was launched.[63] In April 2009, the Real IRA released a statement taking responsibility for the killing.[64]

When Sinn Féin and the Democratic Unionist Party (DUP) became the largest parties, by the terms of the Good Friday Agreement no deal could be made without the support of both parties. They nearly reached a deal in November 2004, but the DUP insisted on photographic and/or video evidence that decommissioning of IRA weapons had been carried out, which was unacceptable to Sinn Féin.[65]

On 2 September 2006, Martin McGuinness publicly stated that Sinn Féin would refuse to participate in a shadow assembly at Stormont, asserting that his party would only take part in negotiations that were aimed at restoring a power-sharing government. This development followed a decision on the part of members of Sinn Féin to refrain from participating in debates since the Assembly's recall the previous May. The relevant parties to these talks were given a deadline of 24 November 2006 to decide upon whether or not they would ultimately form the executive.[66]

The 86-year Sinn Féin boycott of policing in Northern Ireland ended on 28 January 2007, when the Ard Fheis voted overwhelmingly to support the Police Service of Northern Ireland (PSNI).[67] Sinn Féin members began to sit on Policing Boards and join District Policing Partnerships.[68] There was opposition to this decision within Sinn Féin, and some members left, including elected representatives. The most well-known opponent was former IRA prisoner Gerry McGeough, who stood in the 2007 Assembly election against Sinn Féin in the constituency of Fermanagh and South Tyrone, as an Independent Republican.[69] He polled 1.8% of the vote.[70] Others who opposed this development left to found the Republican Network for Unity.

Sinn Fein supported a no vote in the referendum on the Twenty-eighth Amendment of the Constitution Bill 2008.

Immediately after the June 2017 UK general election, where the Conservatives won 49% of seats but not an overall majority, so that non-mainstream parties could have significant influence, Gerry Adams announced for Sinn Féin that their elected MPs would continue the policy of not swearing allegiance to the Queen, as would be required for them to take their seats in the Westminster Parliament.[71]

In 2017 and 2018 there were allegations of bullying within the party, leading to a number of resignations and expulsions of elected members.[72]

At the Ard Fheis on 18 November 2017, Gerry Adams announced he would stand down as president of Sinn Féin in 2018, and would not stand for re-election as TD for Louth.

From 2018

Mary Lou McDonald and Michelle O'Neill in February 2018

On 10 February 2018, Mary Lou McDonald was announced as the new president of Sinn Féin at a special Ard Fheis in Dublin.[73][74][75] Michelle O'Neill was also elected as vice president of the party.[73] McDonald has made clear that as president of Sinn Féin, her ambition is to be in government north and south – and is willing to work in coalition as the major or minor party of government in the southern jurisdiction, a shift in policy compared to Adams' ambition to govern as a minority government in the Oireachtas.

Sinn Féin were opposed to Northern Ireland leaving the European Union together with the rest of the United Kingdom, with Martin McGuinness suggesting a referendum on the reunification of Ireland immediately after the 2016 United Kingdom European Union membership referendum results were announced,[76] a stance later reiterated by Mary Lou McDonald as a way of resolving the border issues raised by Brexit.[77]

In the 2020 Irish general election, Sinn Féin received greatest number of first preference votes nationally, making it the best result for any incarnation of Sinn Féin since the 1922 election however, Fianna Fáil, Fine Gael and the Green Party formed a coalition government in June 2020.[78]

Past links with Republican paramilitaries

Sinn Féin is the largest Irish republican political party, and was historically associated with the IRA, while also having been associated with the Provisional IRA in the party's modern incarnation. The Irish government alleged that senior members of Sinn Féin have held posts on the IRA Army Council.[79] However, the SF leadership has denied these claims.[80]

A republican document of the early 1980s stated: "Both Sinn Féin and the IRA play different but converging roles in the war of national liberation. The Irish Republican Army wages an armed campaign... Sinn Féin maintains the propaganda war and is the public and political voice of the movement".[81] Robert White states at that time Sinn Fein was the junior partner in the relationship with the IRA, and they were separate organisations despite there being some overlapping membership.[82]

The British government stated in 2005 that "we had always said all the way through we believed that Sinn Féin and the IRA were inextricably linked and that had obvious implications at leadership level".[83]

The Northern Bank robbery of £26.5 million in Belfast in December 2004 further delayed a political deal in Northern Ireland. The IRA were widely blamed for the robbery[84] although Sinn Féin denied this and stated that party officials had not known of the robbery nor sanctioned it.[85] Because of the timing of the robbery, it is considered that the plans for the robbery must have been laid whilst Sinn Féin was engaged in talks about a possible peace settlement. This undermined confidence among unionists about the sincerity of republicans towards reaching agreement. In the aftermath of the row over the robbery, a further controversy erupted when, on RTÉ's Questions and Answers programme, the chairman of Sinn Féin, Mitchel McLaughlin, insisted that the IRA's controversial killing of a mother of ten young children, Jean McConville, in the early 1970s though "wrong", was not a crime, as it had taken place in the context of the political conflict. Politicians from the Republic, along with the Irish media, strongly attacked McLaughlin's comments.[86][87]

On 10 February 2005, the government-appointed Independent Monitoring Commission reported that it firmly supported the PSNI and Garda Síochána assessments that the IRA was responsible for the Northern Bank robbery and that certain senior members of Sinn Féin were also senior members of the IRA and would have had knowledge of and given approval to the carrying out of the robbery.[88] Sinn Féin has argued that the IMC is not independent, and that the inclusion of former Alliance Party leader John Alderdice and a British security head was proof of this.[89] The IMC recommended further financial sanctions against Sinn Féin members of the Northern Ireland Assembly. The British government responded by saying it would ask MPs to vote to withdraw the parliamentary allowances of the four Sinn Féin MPs elected in 2001.[90]

Gerry Adams responded to the IMC report by challenging the Irish government to have him arrested for IRA membership—a crime in both jurisdictions—and for conspiracy.[91]

On 20 February 2005, Irish Minister for Justice, Equality and Law Reform Michael McDowell publicly accused three of the Sinn Féin leadership, Gerry Adams, Martin McGuinness and Martin Ferris (TD for Kerry North) of being on the seven-man IRA Army Council; they later denied this.[92][93]

On 27 February 2005, a demonstration against the murder of Robert McCartney on 30 January 2005 was held in east Belfast. Alex Maskey, a former Sinn Féin Lord Mayor of Belfast, was told by relatives of McCartney to "hand over the 12" IRA members involved.[94] The McCartney family, although formerly Sinn Féin voters themselves, urged witnesses to the crime to contact the PSNI.[95][96] Three IRA men were expelled from the organisation, and a man was charged with McCartney's murder.[97][98]

Irish Taoiseach Bertie Ahern subsequently called Sinn Féin and the IRA "both sides of the same coin".[99] In February 2005 Dáil Éireann passed a motion condemning the party's alleged involvement in illegal activity. The Bush Administration did not invite Sinn Féin or any other Northern Irish political party to the annual St Patrick’s Day celebrations at the White House, choosing instead to invite the family of Robert McCartney.[100] Senator Ted Kennedy, a regular sponsor of Gerry Adams' visits to the US during the peace process, also refused to meet Adams and hosted the McCartney family instead.[100]

On 10 March 2005, the House of Commons in London passed without significant opposition a motion, introduced by the British government, to withdraw the allowances of the four Sinn Féin MPs for one year, in response to the Northern Bank Robbery. This measure cost the party approximately £400,000. However, the debate prior to the vote mainly surrounded the more recent events connected with the murder of Robert McCartney. Conservatives and unionists put down amendments to have the Sinn Féin MPs evicted from their offices at the House of Commons but these were defeated.[101]

In March 2005, Mitchell Reiss, the United States Special Envoy for Northern Ireland, condemned the party's links to the IRA, saying "it is hard to understand how a European country in the year 2005 can have a private army associated with a political party".[102]

The October 2015 Assessment on Paramilitary Groups in Northern Ireland concluded that the Provisional IRA still existed "in a much reduced form", and that some IRA members believed its Army Council oversaw both the IRA and Sinn Féin, although it believed that the leadership "remains committed to the peace process and its aim of achieving a united Ireland by political means".[103]

Policy and ideology

Sinn Féin and Republican Youth signs in Strabane

Most of the party's policies are intended to be implemented on an "all-Ireland" basis which further emphasises their central aim of creating a united Ireland.

Sinn Féin is a democratic socialist and left-wing party.[104] In the European Parliament, the party aligns itself with the European United Left–Nordic Green Left (GUE/NGL) parliamentary group. Sinn Féin are pro-immigration on the basis of filling up vacancies in employment, if the system can properly integrate them and resource it, the party also believes in faster application processing times for refugees. Sinn Féin is against "open borders" and believes in abolishing the Direct Provision system.[105] The party aims to eradicate poverty. It is not in favour of the extension of legalised abortion (British 1967 Act) to Northern Ireland, Sinn Féin state they are opposed to the attitudes in society which "pressurise women" to have abortions and "criminalise" women who make this decision. The party does state that in cases of incest, rape, sexual abuse, "fatal foetal abnormalities", or when a woman's life and health are at risk or in danger, the final decision must rest with the woman.[106][107] In the 2018 Irish abortion referendum, the party campaigned for a 'Yes' vote, but remained opposed to abortions up to 12 weeks.[108] Categorised as "populist socialist" in literature,[109] in 2014 leading party strategist and ideologue Eoin Ó Broin described Sinn Féin's entire political project as unashamedly populist.[110]

Sinn Féin has been considered to be Eurosceptic.[111][112] The party campaigned for a "No" vote in the Irish referendum on joining the European Economic Community in 1972.[113] Sinn Féin was on the same side of the debate as the DUP and most of the Ulster Unionist Party (UUP) in that they wanted to pull out when UK had its referendum in 1975.[114] The party was critical of the supposed need for an EU constitution as proposed in 2002,[115] and urged a "No" vote in the 2008 referendum on the Lisbon Treaty, although Mary Lou McDonald said that there was "no contradiction in being pro-Europe, but anti-treaty".[116] In its manifesto for the 2015 UK general election, Sinn Féin pledged that the party would campaign for the UK to stay within the European Union (EU), with Martin McGuinness saying that an exit "would be absolutely economically disastrous". Gerry Adams said that, if there were to be a referendum on the question, there ought to be a separate and binding referendum for Northern Ireland.[117] Its policy of a "Europe of Equals", and its critical engagement after 2001, together with its engagement with the European Parliament, marks a change from the party's previous opposition to the EU. The party expresses, on one hand, "support for Europe-wide measures that promote and enhance human rights, equality and the all-Ireland agenda", and on the other a "principled opposition" to a European superstate.[118] This has led political commentators to define the party as soft Eurosceptic since the 21st century.[119]

Social and cultural

Sinn Féin's main political goal is a united Ireland. Other key policies from their most recent election manifesto are listed below:


  • Increase in capital gains tax and deposit interest retention tax
  • A cap on public sector pay at three times the average worker's wage
  • Standardisation of discretionary tax reliefs
  • Reducing mortgage interest tax relief for landlords and property-based tax reliefs
  • Establishment of a government fund to aid small and medium enterprises
  • An "all-Ireland" economy with a common currency and one tax policy
  • Greater investment for those who are disabled[125]


  • An "All-Ireland-Health-Service" akin to the National Health Service of the United Kingdom
  • Cap on consultants' pay
  • Abolishment of prescription charges for medical card patients
  • Expansion of primary care centres
  • Gradual removal of subsidies of private practice in public hospitals and the introduction of a charge for practitioners for the use of public equipment and staff in their private practice
  • Free breast screening (to check for breast cancer) of all women over forty[126]

International relations

Sinn Féin has longstanding fraternal ties with the African National Congress[127] and was described by Nelson Mandela as an 'old friend and ally in the anti-apartheid struggle'.[128] Sinn Féin supports the independence of Catalonia from Spain,[129] the Palestinians in the Israeli–Palestinian conflict,[130] and the right to self-determination regarding independence of the Basque Country from Spain and France.[131] Sinn Féin opposes the United States embargo against Cuba and has called for a normalization of relations between the two countries.[132] In 2016, the Sinn Féin party president, Gerry Adams was invited by the Cuban government to attend the state funeral of Fidel Castro whom Adams described as a 'freedom fighter' and a 'friend of Ireland's struggle'.[133]

European Union

Sinn Féin support a policy of "critical engagement with the EU", and have a "principled opposition" to a European superstate. It opposes an EU constitution because it would reduce the sovereignty of the member-states.[134][135] It also criticises the EU on grounds of neoliberalism. Sinn Féin MEP Matt Carthy says that the "European Union must become a cooperative union of nation states committed to working together on issues such as climate change, migration, trade, and using our common strengths to improve the lives of citizens. If it does not, EU disintegration becomes a real possibility."[136] The party did, however, support continued UK membership of the European Union in the UK's 2016 EU referendum.[137]

Organisational structure

A Sinn Féin advice centre in Castlewellan

Sinn Féin is organised throughout Ireland, and membership is open to all Irish residents over the age of 16. The party is organised hierarchically into cumainn (branches), comhairle ceantair (district executives), and cúigí (regional executives). At national level, the Coiste Seasta (Standing Committee) oversees the day-to-day running of Sinn Féin. It is an eight-member body nominated by the Sinn Féin Ard Chomhairle (National Executive) and also includes the chairperson of each cúige. The Sinn Féin Ard Chomhairle meets at least once a month. It directs the overall implementation of Sinn Féin policy and activities of the party.[citation needed]

The Ard Chomhairle also oversees the operation of various departments of Sinn Féin, viz Administration, Finance, National Organiser, Campaigns, Sinn Féin Republican Youth, Women's Forum, Culture, Publicity and International Affairs. It is made up of the following: Officer Board and nine other members, all of whom are elected by delegates to the Ard Fheis, fifteen representing the five Cúige regions (three delegates each). The Ard Chomhairle can co-opt eight members for specific posts and additional members can be co-opted, if necessary, to ensure that at least thirty per cent of Ard Chomhairle members are women.[citation needed]

The Ardfheis (national delegate conference) is the ultimate policy-making body of the party, where delegates, directly elected by members of cumainn, can decide on and implement policy. It is held at least once a year, but a special Ard Fheis can be called by the Ard Chomhairle or the membership under special circumstances.[citation needed]

Sinn Féin returned to Northern Ireland elections at the 1982 Assembly elections, winning five seats with 64,191 votes (10.1%). The party narrowly missed winning additional seats in Belfast North and Fermanagh and South Tyrone. In the 1983 UK general election eight months later, Sinn Féin increased its support, breaking the six-figure vote barrier in Northern Ireland for the first time by polling 102,701 votes (13.4%).[138] Gerry Adams won the Belfast West constituency, and Danny Morrison fell only 78 votes short of victory in Mid Ulster.

The 1984 European elections proved to be a disappointment, with Sinn Féin's candidate Danny Morrison polling 91,476 (13.3%) and falling well behind the SDLP candidate John Hume.

By the beginning of 1985, Sinn Féin had won its first representation on local councils, owing to three by-election wins in Omagh (Seamus Kerr, May 1983) and Belfast (Alex Maskey in June 1983 and Sean McKnight in March 1984). Three sitting councillors also defected to Sinn Féin in Dungannon, Fermanagh and Derry (the last defecting from the SDLP).[139][140][141] Sinn Féin succeeded in winning 59 seats in the 1985 local government elections, after it had predicted winning only 40 seats. However, the results continued to show a decline from the peak of 1983, as the party won 75,686 votes (11.8%).[141] The party failed to gain any seats in the 1986 by-elections caused by the resignation of unionist MPs in protest at the Anglo-Irish Agreement. While this was partly due to an electoral pact between unionist candidates, the SF vote fell in the four constituencies they contested.[142]

In the 1987 general election, Gerry Adams held his Belfast West seat, but the party failed to make breakthroughs elsewhere and overall polled 83,389 votes (11.4%).[143] The same year saw the party contest the Dáil election in the Republic of Ireland; however, it failed to win any seats and polled less than 2%.

The 1989 local government elections saw a drop in support for Sinn Féin.[144] Defending 58 seats (the 59 won in 1985, plus two 1987 by-election gains in West Belfast, minus three councillors who had defected to Republican Sinn Féin in 1986), the party lost 15 seats. In the aftermath of the election, Mitchell McLaughlin admitted that recent IRA activity had affected the Sinn Féin vote.[145]

In the 1989 European election, Danny Morrison again failed to win a seat, polling at 48,914 votes (9%).

The nadir for SF in this period came in 1992, with Gerry Adams losing his Belfast West seat to the SDLP, and the SF vote falling in the other constituencies that they had contested relative to 1987.[146]

In the 1997 UK general election, Adams regained Belfast West. Martin McGuinness also won a seat in Mid Ulster. In the Irish general election the same year the party won its first seat since 1957, with Caoimhghín Ó Caoláin gaining a seat in the Cavan–Monaghan constituency. In the Irish local elections of 1999 the party increased its number of councillors from 7 to 23.

The party overtook its nationalist rival, the Social Democratic and Labour Party, as the largest nationalist party in the local elections and UK general election of 2001, winning four Westminster seats to the SDLP's three.[147] The party continues to subscribe, however, to an abstentionist policy towards the Westminster British parliament, on account of opposing that parliament's jurisdiction in Northern Ireland, as well as its oath to the Queen.[148][149]

Results in Northern Ireland from UK general elections. Sinn Féin increased its number of seats from two in 1997 to five in 2005, four of them in the west. It retained its five seats in 2010, was reduced to four in 2015 before increasing to seven in 2017.

Sinn Féin increased its share of the nationalist vote in the 2003, 2007, and 2011 Assembly elections, with Martin McGuinness, former Minister for Education, taking the post of deputy First Minister in the Northern Ireland power-sharing Executive Committee. The party has three ministers in the Executive Committee.

In the 2010 general election, the party retained its five seats,[150] and for the first time topped the poll at a Westminster election in Northern Ireland, winning 25.5% of the vote.[151] All Sinn Féin MPs increased their share of the vote and with the exception of Fermanagh and South Tyrone, increased their majorities.[150] In Fermanagh and South Tyrone, Unionist parties agreed a joint candidate,[152] this resulted in the closest contest of the election, with Sinn Féin MP Michelle Gildernew holding her seat by 4 votes after 3 recounts and an election petition challenging the result.[153]

Sinn Féin lost some ground in the 2016 Assembly election, dropping one seat to finish with 28, ten behind the DUP.[154] In the snap election eight months later caused by the resignation of McGuinness as deputy First Minister, however, the party surged, winning 27.9% of the popular vote to 28.1% for the DUP, and 27 seats to the DUP's 28 in an Assembly reduced by 18 seats.[155][156] The withdrawal of the DUP party whip from Jim Wells in May 2018 meant that Sinn Féin became the joint-largest party in the Assembly alongside the DUP, with 27 seats each.[157]

The party had five TDs elected in the 2002 Irish general election, an increase of four from the previous election. At the general election in 2007 the party had expectations of substantial gains,[158][159] with poll predictions that they would gain five[160] to ten seats.[161] However, the party lost one of its seats to Fine Gael. Seán Crowe, who had topped the poll in Dublin South-West fell to fifth place, with his first preference vote reduced from 20.28% to 12.16%.[162]

On 26 November 2010, Pearse Doherty won a seat in the Donegal South-West by-election. It was the party's first by-election victory in the Republic of Ireland since 1925.[163] After negotiations with the left-wing Independent TDs Finian McGrath and Maureen O'Sullivan, a Technical Group was formed in the Dáil to give its members more speaking time.[164][165]

In the 2011 Irish general election the party made significant gains. All its sitting TDs were returned, with Seán Crowe regaining the seat he had lost in 2007 in Dublin South-West. In addition to winning long-targeted seats such as Dublin Central and Dublin North-West, the party gained unexpected seats in Cork East and Sligo–North Leitrim.[166] It ultimately won 14 seats, the best performance at the time for the party's current incarnation. The party went on to win three seats in the Seanad election which followed their success at the general election.[167] In the 2016 election it made further gains, finishing with 23 seats and overtaking the Labour Party as the third-largest party in the Dáil.[168] It ran seven candidates in the Seanad election, all of whom were successful.[169]

The party achieved their greatest contemporary result in the 2020 Irish general election, topping the first-preference votes with 24.5% and winning 37 seats. Due to poor results in the 2019 local elections and elections to the European Parliament, the party ran only 42 candidates and did not compete in Cork North-West. The party achieved unexpected success in the early counting, with 27 candidates being elected on the first count.[170][171] Party leader Mary Lou McDonald called the result a "revolution" and announced she would pursue the formation of a government including Sinn Féin.[172] Ultimately negotiations to form a new government led to Fianna Fáil, Fine Gael and the Green Party agreeing to enter a majority coalition government in June. Sinn Féin pledged to be a strong opposition to the new coalition.[173]

Sinn Féin is represented on most county and city councils. It made large gains in the local elections of 2004, increasing its number of councillors from 21 to 54, and replacing the Progressive Democrats as the fourth-largest party in local government.[174] At the local elections of June 2009, the party's vote fell by 0.95% to 7.34%, with no change in the number of seats. Losses in Dublin and urban areas were balanced by gains in areas such as Limerick, Wicklow, Cork, Tipperary and Kilkenny and the border counties .[175] However, three of Sinn Féin's seven representatives on Dublin City Council resigned within six months of the June 2009 elections, one of them defecting to the Labour Party.[176]

In the 2004 European Parliament election, Bairbre de Brún won Sinn Féin's first seat in the European Parliament, at the expense of the SDLP. She came in second behind Jim Allister of the DUP.[177] In the 2009 election, de Brún was re-elected with 126,184 first preference votes, the only candidate to reach the quota on the first count. This was the first time since elections began in 1979 that the DUP failed to take the first seat, and was the first occasion Sinn Féin topped a poll in any Northern Ireland election.[178][179]

Sinn Féin made a breakthrough in the Dublin constituency in 2004. The party's candidate, Mary Lou McDonald, was elected on the sixth count as one of four MEPs for Dublin.[180] In the 2009 election, when Dublin's representation was reduced to three MEPs, she failed to hold her seat.[181] In the South constituency their candidate, Councillor Toiréasa Ferris, managed to nearly double the number of first preference votes,[181] lying third after the first count, but failed to get enough transfers to win a seat. In the 2014 election, Martina Anderson topped the poll in Northern Ireland, as did Lynn Boylan in Dublin. Liadh Ní Riada was elected in the South constituency, and Matt Carthy in Midlands–North-West.[182] In the 2019 election, Carthy was re-elected, but Boylan and Ní Riada lost their seats. Anderson also held her Northern Ireland seat until early 2020 when her term was cut short by Brexit.[183]
