The agreement was formally concluded between the British and Irish governments as well as eight northern Ireland political parties, including Sinn Féin, the Ulster Unionist Party, the SDLP and the Alliance Party. The DUP was the only major political group to oppose it. As a result, until 2017, Northern Ireland`s policy was again polarized from a denominational point of view to the point that Community cooperation at the heart of the Good Friday Agreement could no longer work. The immediate causes of the collapse of power-sharing were union opposition to the legal status of the Irish indigenous language and the refusal of DUP Premier Arlene Foster at the time to resign over a fuel subsidy scandal. The DUP-Sinn Féin coalition, still a marriage of cold complacents, has collapsed after 10 years of living together. In recent days, Mr Blair and Irish Prime Minister Bertie Ahern have travelled to Belfast to participate in the talks and the agreement was finally announced by George Mitchell on the afternoon of 10 April 1998. This is because the Good Friday Agreement has created complex agreements between the various parties. The three areas of action of the pact have created a network of institutions to govern Northern Ireland (Strand One), bring together the heads of state and government in Northern Ireland with those of Ireland (Strand Two or North-South Cooperation) and bring together heads of state and government from across the United Kingdom and Ireland (Beach 3 or East-West). There are currently more than 140 areas in Northern Ireland-Republic of Ireland, cross-border cooperation, including health services, energy infrastructure and police work. Many experts and political leaders fear that any disruption of this cooperation could undermine confidence in the agreement and hence the basis for peace in Northern Ireland. The Good Friday Agreement (GFA) or the Belfast Agreement (irish: Comhaonté Aoine an Chéasta or Comhaonté Bhéal Feirste; Ulster-Scots: Guid Friday Greeance or Bilfawst Greeance) is a couple of agreements signed on 10 April 1998 that put an end to most of the violence of the Troubles, a political conflict in Northern Ireland that had erupted since the late 1960s.
This was an important development in the Northern Ireland peace process in the 1990s. Northern Ireland`s current system of de-decentralized government is based on the agreement. The agreement also created a number of institutions between Northern Ireland and the Republic of Ireland, as well as between the Republic of Ireland and the United Kingdom. On 27 March 2007, the party`s only MEP, Jim Allister, left the party, contrary to the decision to form a government with Sinn Féin. He retained his seat as an independent MP as chairman of his new radical party against the St Andrews Agreement, which he formed along with other disgruntled members who had left the DUP in this case, traditional Unionist Voice, a seat he retained until Diane Dodds returned to the DUP in 2009. On April 6, 2007, MP Gregory Campbell warned that his party would be monitoring the benefits of its power-sharing agreement with Sinn Féin.  The agreement reaffirmed its commitment to “mutual respect, civil rights and religious freedoms for all in the Community.”
