Support The
British House of Commons voted for a motion to approve the Agreement by a majority of 426 (473 for and 47 against, the biggest majority during Thatcher's premiership). Most of the Conservative members voted for it, although there were some unionists in the party who opposed it, as well as some members of the
Labour Party and the
Liberal-
SDP Alliance. Of the main parties in Northern Ireland, only the nationalist
Social Democratic and Labour Party (SDLP) and the cross community
Alliance Party supported the agreement, although the Alliance Party did not have any seats at Westminster. The Agreement was approved by
Dáil Éireann, by 88 votes to 75, and by
Seanad Éireann by 37 votes to 16. The
Irish nationalist Fianna Fáil, at the time the main opposition party in Ireland, also rejected the Agreement. The Fianna Fáil leader,
Charles Haughey, claimed the Agreement was in conflict with
Articles 2 and 3 of the Constitution of Ireland because it officially recognised British jurisdiction in Northern Ireland. It was also opposed by the Independent Republican
TDs
Neil Blaney and
Tony Gregory, FitzGerald's government's approval ratings went up 10% to 34%; 32% approved of Haughey's opposition to the Agreement, with 56% opposed. There was also a mass rally outside
Belfast City Hall on 23 November 1985 against the Agreement, with Irish historian
Jonathan Bardon saying of it: "Nothing like it had been seen since 1912". Estimates of the number of people there vary:
The Irish Times claimed 35,000 people were present; the
News of the World,
The Sunday Times and the
Sunday Express claimed 100,000; the lecturer in Politics at the
University of Ulster, Arthur Aughey, claimed over 200,000 people were there; and the organisers of the meeting said 500,000 attended. Following the resignation of the unionist members of parliament, who represented 15 of the 17 Westminster seats in the province, the
1986 Northern Ireland by-elections were held on 23 January 1986, and all the resigning members except one were re-elected, standing on an anti-Agreement platform. The exception was
Newry and Armagh, which in a close contest was gained by the pro-Agreement SDLP. On 3 March 1986 there was a general strike, or 'Day of Action', in Northern Ireland, in opposition to the Anglo-Irish Agreement. There was widespread disruption as workplaces closed. Public transport including air travel was also affected. There was significant genuine Protestant support for the strike but there was also a high level of intimidation with masked Loyalists establishing barricades. In Portadown mobs attacked Catholic homes and a section of the motorway near Belfast way closed after nails and oil were strewn across the road. There were riots in Loyalist areas during the evening and night and shots were fired at the
Royal Ulster Constabulary (RUC). Later RUC figures stated that there had been 237 reported cases of intimidation, 57 people arrested, and 47 RUC officers injured. The British government and the security forces were later criticised for not keeping arterial routes open and for not trying to end the intimidation.
Alliance Party politician
Seamus Close, whose family had been a victim of intimidation, criticised UUP leader Jim Molyneaux for downplaying reports of intimidation. DUP Chief Whip
Jim Allister denied roadside pickets which surrounded motorists amounted to intimidation. Attacks on RUC officers' homes had already started in the summer of 1985 with unionist resentment exacerbated by the RUC rerouting
Orange Order and other Protestant
fraternal societies away from Catholic areas in 1985 and 1986. The UUP MP
Enoch Powell asked Thatcher in the Commons the day before she signed the Agreement: "Does the Right Hon. Lady understand—if she does not yet understand she soon will—that the penalty for treachery is to fall into public contempt?" The UUP leader
James Molyneaux spoke of "the stench of hypocrisy, deceit and treachery" and later said of "universal cold fury" at the Agreement such as he had not experienced in forty years of public life. Ian Paisley, a few days later to his congregation, compared Thatcher to "
Jezebel who sought to destroy Israel in a day". He wrote to Thatcher: "Having failed to defeat the IRA you now have capitulated and are prepared to set in motion machinery which will achieve the IRA goal... a united Ireland. We now know that you have prepared Ulster Unionists for sacrifice on the altar of political expediency. They are to be the sacrificial lambs to appease the Dublin wolves". In his letter to FitzGerald, Paisley said: "You claim in your constitution jurisdiction over our territory, our homes, our persons and our families. You allow your territory to be used as a launching pad for murder gangs and as a sanctuary for them when they return soaked in our people's blood. You are a fellow traveller with the IRA and hope to ride on the back of their terrorism to your goal of a United Ireland. We reject your claims and will never submit to your authority. We will never bow to Dublin rule". The moderator of the
Presbyterian Church of Ireland, Robert Dickinson, wrote to Thatcher and said the Agreement was "the beginning of the process of edging Northern Ireland out of the United Kingdom – sovereignty has been impinged". Thatcher's close friend and former Parliamentary Private Secretary
Ian Gow resigned from his Treasury post in protest at the Agreement. UUP politicians Christopher and
Michael McGimpsey even brought a suit against the Irish government in the
High Court of Ireland, arguing that the Agreement was invalid because it contradicted
Articles 2 and 3 of the Constitution of Ireland. (This argument was unusual coming from a unionist because of the traditional unionist opposition to these two articles.) The case failed in the High Court, and again on appeal to the
Supreme Court. Concerns of a
Rhodesia-style unilateral declaration of independence (UDI) were raised repeatedly during several confidential Anglo-Irish meetings in 1986, according to Irish State papers declassified in 2016. Taoiseach Garret Fitzgerald believed that keeping the
Northern Ireland Assembly running ran the risk of it being used to declare Northern Ireland independent from Britain. Some senior Unionist politicians were sympathetic to the idea and had grown closer to loyalist paramilitaries, including DUP deputy leader
Peter Robinson and UUP
MP Harold McCusker. British civil service head Sir Robert Armstrong said that Unionist politicians had not considered the financial implications of an independent Northern Ireland, or how the move would be perceived internationally, especially in the context of the
European Economic Community (EEC). In 1990 Thatcher said that "The Anglo-Irish Agreement had alienated some pro-Ulster supporters in crucial constituencies" in Scotland. In August 1986 DUP Deputy Leader
Peter Robinson led a loyalist '
invasion' of the village of
Clontibret in the Republic of Ireland, near the border. The loyalists vandalised many buildings and beat up two police officers. Robinson was arrested, leading to rioting before and after his trial. In November 1986 at an invitation-only ceremony at the
Ulster Hall the DUP launched
Ulster Resistance, a new paramilitary organisation intended to oppose the Anglo-Irish Agreement and fight Irish Republicanism.
Ivan Foster claimed the group already had access to a significant arsenal of legally-owned firearms. The weapons jointly imported by Ulster Resistance and the two main Loyalist paramilitary organisations were linked to over 70 murders, including the
Greysteel massacre and the
Loughinisland massacre. Thatcher was taken aback by the ferocity of the Unionist response and in her memoirs she said their reaction was "worse than anyone had predicted to me". She furthermore claimed that the Agreement was in the tradition of British governments refraining "from security policies that might alienate the Irish Government and Irish nationalist opinion in Ulster, in the hope of winning their support against the IRA". However, Thatcher perceived the results of this to be disappointing because "our concessions alienated the Unionists without gaining the level of security co-operation we had a right to expect. In the light of this experience it is surely time to consider an alternative approach". In 1998 Thatcher said she regretted signing the Agreement and said of Enoch Powell's opposition to the Agreement: "I now believe that his assessment was right". Prominent
Irish Labour Party member
Mary Robinson, who subsequently became
President of Ireland, resigned from the Irish Labour Party because she believed that the Agreement "could not achieve its objective of securing peace and stability within Northern Ireland... because... it would be unacceptable to all sections of Unionist opinion". On the other hand, the IRA and Sinn Féin said that the concessions made by Great Britain were the result of its armed campaign, from which the SDLP gained political credit. Brian Feeney of the SDLP has suggested the agreement hastened Sinn Féin's 1986 decision to abandon
abstentionism from the Republic's
Oireachtas. Speaking in the House of Commons
Jeremy Corbyn, MP for
Islington North and later
Labour leader, spoke to oppose the treaty saying that it ran counter to the goal of a
United Ireland: Does the hon. Gentleman accept that some of us oppose the agreement for reasons other than those that he has given? We believe that the agreement strengthens rather than weakens the border between the six and the 26 counties, and those of us who wish to see a United Ireland oppose the agreement for that reason. He then went on to express concerns that the agreement threatened
Irish neutrality and risked forcing the Republic of Ireland to accept the British presence in Northern Ireland. The former cabinet minister
Tony Benn and
Ken Livingstone, then leader of the
Greater London Council, also opposed the agreement because they believed Britain should withdraw from Northern Ireland.
Northern Ireland by-elections The by-elections called after the Unionist MPs resigned did not quite offer the electorate a clear-cut choice on the agreement due to the reluctance of the other parties to contest them. No unionist candidate opposed another, whilst both the SDLP and
Sinn Féin only contested the four seats where at the previous election there had been a majority of votes cast for nationalist candidates. The SDLP rejected a Sinn Féin offer to form a nationalist electoral pact to oppose the unionist electoral pact. In the process the SDLP gained the
Newry and Armagh seat. The Alliance formally committed to fighting all the seats on a platform of support for the Agreement, but some local branches declined to select candidates. The
Workers' Party stood in a few seats. In four constituencies where no party would oppose the Unionist MP a man called
Wesley Robert Williamson changed his name by
deed poll to "
Peter Barry" (the name of the Irish Foreign Minister) and stood on the label "For the Anglo-Irish Agreement" but did not campaign. Despite this he garnered nearly 7,000 votes and saved three deposits. The unionist parties between them garnered over 400,000 votes and over 71% of the total poll, but as no by-elections took place in the staunch nationalist seats of
West Belfast and
Foyle this latter figure is skewed. ==Long-term effects==
