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. The participants in the agreement were composed of two sovereign states (the United Kingdom and the Republic of Ireland), with armed forces and police forces involved in the riots. Two political parties, Sinn Féin and the Progressive Unionist Party (PUP), were linked to paramilitary organisations: the IRA (Commissional Irish Republican Army) and the Ulster Volunteer Force (UVF). The Ulster Democratic Party (UDP), associated with the Ulster Defence Association (UDA), had withdrawn from the talks three months earlier. The result of these referendums was a large majority in both parts of Ireland in favour of the agreement. In the Republic, 56% of the electorate voted, 94% of the vote voted in favour of the revision of the Constitution. The turnout was 81% in Northern Ireland, with 71% of the vote for the agreement. 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.  The agreement sets out a framework for the creation and number of institutions in three “parts.” The agreement reaffirmed its commitment to “mutual respect, civil rights and religious freedoms for all within the Community.” The multi-party agreement recognized “the importance of respect, understanding and tolerance with regard to linguistic diversity,” particularly with regard to the Irish language, Ulster Scots and the languages of other ethnic minorities in Northern Ireland, “all of which are part of the cultural richness of the Island of Ireland.” During negotiations on the UK`s planned withdrawal from the European Union in 2019, the EU presented a position paper on its concerns about Britain`s support for the Good Friday agreement during Brexit. The position paper deals with issues such as the prevention of a hard border, north-south cooperation between the Republic of Northern Ireland, the birthright of all Northern Ireland residents (as stated in the agreement) and the common travel area.   Anyone who was born in Northern Ireland and is therefore entitled to an Irish passport under the Good Friday Agreement may retain European citizenship after Brexit.  As part of the EU`s Brexit negotiating guidelines, the UK was asked to convince other EU members that these issues had been addressed in order to enter the second phase of the Brexit negotiations. In order to protect North-South cooperation and avoid controls at the Irish border, the United Kingdom, under the leadership of Prime Minister Theresa May, said it was ready to protect the agreement in all its parties and “in the absence of agreed solutions, the Uk would maintain full alignment with the rules of the internal market and customs union, which are now or in the future. , North-South cooperation supporting the island`s economy and protecting the 1998 agreement” by acknowledging that “it is the restriction that nothing is agreed until everything has been agreed”.     This provision was part of an agreement between the United Kingdom and the EU, which was rejected three times by the British Parliament.  May`s successor, Prime Minister Boris Johnson, initially cited the “Irish backstop” that was to be withdrawn from the proposed agreement, but finally accepted it after the negotiation of a new agreement between the UK and the EU on 17 October 2019.
  In September 2020, northern Ireland Secretary Brandon Lewis informed the House of Commons that the British government intended to violate international law in a “specific and limited” manner by introducing a new bill that gives the British government new national powers to circumvent certain contra obligations.
