The Social Democratic and Labour Party (SDLP; ) is a social democratic and Irish nationalist political party in Northern Ireland. The SDLP currently has eight members in the Northern Ireland Assembly (MLAs) and two members of Parliament (MPs) in the House of Commons of the United Kingdom.

The SDLP party platform advocates Irish reunification and, pending the unity of all the people of Ireland and while the northern jurisdiction remains part of the United Kingdom, further devolution of powers. It is a sister party of the UK Labour Party, which maintains an electoral pact with the SDLP not to stand candidates in Northern Ireland but to support SDLP candidates instead. MPs from the SDLP sit with Labour MPs on the government benches when Labour is in power, but do not take the Labour whip, though they informally did so historically.Understanding Ulster by Antony Alcock, Ulster Society Publications, 1997.

During the Troubles, the SDLP was the most popular Irish nationalist party in Northern Ireland, but since the Provisional IRA ceasefire in 1994, it has lost ground to the republican party Sinn Féin, which in 2001 became the more popular of the two parties for the first time. Established during the Troubles, a significant difference between the two parties was the SDLP's rejection of violence, in contrast to Sinn Féin's then-support for (and organisational ties to) the Provisional IRA and physical force republicanism.

Ideology and policies

The SDLP is a social democratic party that opposes austerity and Brexit.

The party is an Irish nationalist party advocating for a united Ireland, however, unlike the other nationalist party Sinn Féin, the party is viewed as more pragmatic and moderate on the subject. For example, unlike Sinn Féin they are not calling for an immediate date for a border poll. The SDLP is not abstentionist in regards to Westminster and the party cooperates fully with UK political and constitutional institutions.

While the party is officially anti-abortion, it does not apply a party whip on the issue. They also are "open to a change in the law" on assisted dying. The party supports LGBT rights including marriage equality, the roll out of PrEP across Northern Ireland and LGBT education in schools. The SDLP is anti-xenophobic and opposes plans to create what it deems a hostile environment for immigrants. The party also supports an Irish language act.

The SDLP believes that 3,000 social and affordable houses should be built every year. They oppose the gig economy and zero-hour contracts. The party opposes welfare reform and the cut to universal credit.

Despite opposing academic selection, the party does not advocate the abolition of grammar schools. The party supports the abolition of tuition fees. It wants to make a modern language up to GCSE and the teaching of maths up to the age of 18 compulsory.

The party believes that the Magee campus in Derry should be expanded to 10,000 student places.

The party supports a green corporate levy on businesses who contribute large amounts of greenhouse gases and a green jobs strategy. They also believe that a climate emergency should be declared and the government should be required to reach net zero emissions.

History Foundation and early history (1970–1972) The party was founded on 21 August 1970, when six Stormont MPs (Gerry Fitt, Republican Labour Party; Austin Currie, Nationalist Party; Paddy Devlin, Northern Ireland Labour Party; John Hume, Ivan Cooper and Paddy O'Hanlon, Independent) and one Senator (Paddy Wilson, Republican Labour), joined to form a new party. They were joined on 10 November by a second Senator (Claude Wilton, Ulster Liberal Party), bringing the total parliamentary party to eight members. Gerry Fitt was chosen to lead the new party while John Hume was appointed its deputy. Paddy Wilson also became the party's first General Secretary.

The smaller National Democratic Party dissolved itself in October of that year and encouraged all its members to join the new party. Additionally, individual members and branches from other parties joined including from the Irish Labour Party, Nationalist Party, Northern Ireland Labour Party, Republican Labour Party and Ulster Liberal Party.

The SDLP contested its first election in a by-election for the Belfast St. Anne's seat on 12 November. Their candidate Gerry Laverty won 24.2% of the vote in the traditionally Unionist seat.

The SDLP initially rejected the Nationalist Party's policy of abstentionism and sought to fight for civil rights within the Stormont system. However, the SDLP quickly came to the view that Stormont was unreformable, refusing to attend the state opening on 18 June 1971, and withdrawing altogether in response the shooting dead of Seamus Cusack and Desmond Beattie in Derry on 8 July.

On 15 August the SDLP announced they would lead a Campaign of Civil Disobedience in response to the introduction of internment the previous week. This involved the withdrawal of SDLP representatives from public bodies, the organisation of a rent and rates strike and SDLP MPs participating in a 48 hour hunger strike outside 10 Downing Street.

The SDLP held its first annual conference in Dungiven on 23 October that year. The party adopted its draft constitution, Eddie McGrady was elected the party's first chairman while Sheila Carson becomes its first secretary. Several motions were passed including committing the party firmly to socialism, supporting the parliamentary party's decision to withdraw from Stormont and condemning the 11-plus.

After the abolition of the Parliament of Northern Ireland in 1972, the SDLP emerged as the largest party representing the nationalist community. On 20 September the party issued its first major policy document, entitled "Towards a New Ireland". It recommended that the British Government issue a declaration that it would recognise that Ireland is better off united, and that as an interim proposal Northern Ireland should be administered jointly by the British and Irish Governments. It also proposed the establishment of a National Senate drawn equally from a devolved Assembly in Belfast and the Oireachtas in Dublin to plan for the integration of the island.

Sunningdale Agreement (1973–1974) The first major electoral contest for the SDLP were elections to Northern Ireland's 26 new district councils, held on 30 May 1973. The SDLP won 13.4% of the vote and 82 seats, becoming the second largest party in Northern Ireland and the largest party in the districts of Derry, Magherafelt and Newry and Mourne. Other nationalist parties failed to achieve much success, leaving the SDLP as the largest party representing the nationalist community.

Paddy Wilson, the SDLP's General Secretary and councillor in the new Belfast City Council was murdered on the 26 June, two days before the election to the new Northern Ireland Assembly. Wilson and another woman, Irene Andrews, were killed by the UFF, a codename for the UDA. John White was later convicted for his part in the killings.

Following publication of the British Government's White Paper, elections were held to the new Northern Ireland Assembly on 28 June, where the party won 19 out of 75 seats and once again emerged as the voice of the nationalist community, increasing its vote share to 22% of the vote. Negotiations occurred throughout October and November on the formation of a new power-sharing Executive to govern Northern Ireland with the SDLP, UUP and Alliance taking part. On 21 November Northern Ireland Secretary of State, William Whitelaw, announced that agreement had been reached on the composition and functions of the new Executive, with the SDLP entitled to four of the eleven members and a further two non-Executive office holders. Agreement was still to be reached on many other aspects of the White Paper, particularly regarding the Council of Ireland.

Following discussions between the British Prime Minister and Irish Taoiseach, as well as the political parties, it was announced on 9 December at Sunningdale that an agreement had been reached on the remaining elements of the White Paper, including the implementation of a Council of Ireland.

On 1 January 1974 the Northern Ireland Executive took office, with Gerry Fitt as Deputy Chief Executive, John Hume as Minister of Commerce, Paddy Devlin as Minister of Health and Social Services and Austin Currie as Minister of Housing, Local Government and Planning.

The SDLP faced its first Westminster election shortly afterwards in February in what became a referendum on power-sharing. The anti-power-sharing Unionists united under the UUUC banner and won 11 seats, with Gerry Fitt being the only pro-power-sharing MP returned, dealing a critical blow to the fledgling Executive. The Executive eventually collapsed after 5 months following several weeks of the Ulster Workers' Council strike.

Searching for agreement (1975–1980) Attempting to find agreement, the Secretary of State called elections for a Constitutional Convention on 1 May 1975, for which the SDLP won 17 seats and 24% of the vote. The UUUC however won a majority of seats and votes, the Constitutional Convention made no progress and the British Government brought it to an end in early 1976. Later that year on 1 September SDLP member Denis Mullen was shot dead at his home.

Following the failure of the Constitutional Convention the SDLP continued searching for a long term solution, at times engaging in talks with the UUP. In 1977 the party issued a policy document titled "Facing Reality". This called for the party to put a stronger emphasis on the "Irish dimension". In response to this perceived move away from the party's Labour values Paddy Devlin, then party chairperson, resigned from the party.

In 1978 SDLP deputy leader John Hume presented his proposal for an "agreed Ireland". In contrast to the two main options at the time of full integration into Britain or full withdrawal, Hume's solution proposed the British government declaring that its aim was to bring the main traditions in Ireland together in reconciliation.

After years of little progress 1979 brought considerably more action for the SDLP. A vote of confidence in the Labour Government failed in March that year. Gerry Fitt abstained on the vote as the Government had failed to act on the Bennett Report into RUC interrogation techniques. In the following general election, the Conservatives came to power in Westminster and Fitt held his seat in Belfast West.

In June that year the first direct election to the European Parliament were held. The SDLP candidate was John Hume who won a seat with 25% of the first preference vote. He went on to sit in the Socialist Group in the European Parliament.

The new Conservative Secretary of State, Humphrey Atkins, invited Northern Ireland parties including the SDLP to a conference on the future of Northern Ireland. There was intense debate in the SDLP whether or not to attend a conference which would not discuss any all-island dimension, with Gerry Fitt wanting to attend regardless of any discussion on an "Irish dimension" while many others, including John Hume, refusing to attend. As a result of this dispute Fitt resigned as SDLP leader. On 28 November John Hume was elected as his replacement, and Seamus Mallon became his deputy.

The SDLP eventually made the decision to attend the Atkins conference, on the condition that there would be parallel discussions involving the "Irish dimension". These talks, like others, failed to reach agreement.
