Northern Ireland political parties that approved the agreement were also invited to consider the creation of an independent advisory forum, which would represent civil society, with members with expertise on social, cultural, economic and other issues, and would be appointed by both administrations. In 2002, a framework structure was agreed for the North-South Advisory Forum, and in 2006 the Northern Ireland Executive agreed to support its implementation. 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. The agreement was reached between the British and Irish governments as well as eight northern Ireland political parties or groups. Three were representative of unionism: the Ulster Unionist Party, which had led unionism in Ulster since the early 20th century, and two small parties linked to loyalist paramilitaries, the Progressive Unionist Party (linked to the Ulster Volunteer Force (UVF) and the Ulster Democratic Party (the political wing of the Ulster Defence Association (UDA). Two of them have been widely described as nationalists: the Social Democratic and Labour Party and Sinn Féin, the Republican party affiliated with the Provisional Republican Army.   Apart from these rival traditions, there were two other assemblies, the Inter-Community Alliance Party and the Northern Ireland Women`s Coalition.
There was also the Labour coalition. U.S. Senator George J. Mitchell was sent by U.S. President Bill Clinton to chair the talks between parties and groups.  The Protocol on Ireland and Northern Ireland, which is included in the UK`s withdrawal agreement from the EU, confirmed that the Good Friday Agreement must be protected in all its parts. The British government is virtually out of the game and neither parliament nor the British people have, as part of this agreement, the legal right to obstruct the achievement of Irish unity if it had the consent of the people of the North and The South… Our nation is and will remain a nation of 32 circles. Antrim and Down are and will remain a part of Ireland, just like any southern county.  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. On 11 January 2020, on the basis of the New Decade Agreement, the new concept, the executive and the Power-Sharing Assembly, the Executive and the Assembly were reinstated, to the participation of the five main political parties in Northern Ireland. As part of the agreement, it was proposed to build on the existing Inter-Parliamentary Commission in English-Irish. Prior to the agreement, the body was composed only of parliamentarians from the British and Irish assemblies. In 2001, as proposed by the agreement, it was extended to include parliamentarians of all members of the Anglo-Irish Council.
