In 2004, negotiations were held between the two governments, the DUP, and Sinn Féin, for an agreement to restore the institutions. The talks failed, but a document published by governments detailing the changes to the Belfast agreement was known as the “comprehensive agreement.” However, on 26 September 2005, it was announced that the Provisional Republican Army of Ireland had completely closed its arsenal of weapons and had “taken it out of service”. Nevertheless, many trade unionists, especially the DUP, remained skeptical. Among the loyalist paramilitaries, only the Loyalist Volunteer Force (LVF) had decommissioned all weapons.  Further negotiations took place in October 2006 and resulted in the St Andrews Agreement. The agreement was approved by voters across the island of Ireland in two referendums on 22 May 1998. In Northern Ireland, in the 1998 referendum on the Good Friday Agreement in Northern Ireland, voters were asked if they supported the multi-party agreement. In the Republic of Ireland, voters were asked whether they would allow the state to sign the agreement and authorize the necessary constitutional changes (nineteen constitutional amendments from Ireland) to facilitate it. The citizens of both countries had to approve the agreement to implement it. As part of the agreement, the British and Irish governments committed to holding referendums in Northern Ireland and the Republic on 22 May 1998. The referendum on Northern Ireland is expected to approve the deal reached at the multi-party talks. The Republic of Ireland`s referendum should approve the Anglo-Irish agreement and facilitate the modification of the Irish constitution in accordance with the agreement. This conference takes the form of regular and frequent meetings between The British and Irish ministers to promote cooperation between the two governments at all levels.
On issues not left to Northern Ireland, the Irish government can present views and proposals. All decisions of the Conference are taken by mutual agreement between the two governments and the two governments, in order to make resolute efforts to resolve the differences between them. Direct domination of London ended in Northern Ireland when power was formally transferred to the new Northern Ireland Assembly, the North-South Council and the Anglo-Irish Council when the opening decisions of the Anglo-Irish Agreement came into force on 2 December 1999.    Article 4, paragraph 2 of the Anglo-Irish Agreement (the agreement between the British and Irish governments on the implementation of the Belfast Agreement) required both governments to inquire in writing about compliance with the terms of entry into force of the Anglo-Irish Agreement; The latter is expected to come into effect as soon as both notifications are received.  The British government has agreed to participate in a televised ceremony at Iveagh House in Dublin, the Irish Foreign Office. Peter Mandelson, Minister of Northern Ireland, participated in his participation in early December 2, 1999. He exchanged notifications with David Andrews, the Irish Foreign Secretary. Shortly after the ceremony, at 10:30 a.m., the Taoiseach, Bertie Ahern, signed the declaration of formal amendment of Articles 2 and 3 of the Irish Constitution.
He then informed the D`il that the Anglo-Irish agreement had entered into force (including some endorsements to the Belfast Agreement).   The vague wording of some of the so-called “constructive ambiguities” helped ensure the adoption of the agreement and allowed for a postponement of debate on some of the most controversial issues. These include extra-military dismantling, police reform and the standardisation of Northern Ireland. The final withdrawal agreement between the EU and the UK has agreed on a complex solution to this delicate problem.
