However, the agreement has also been the subject of a wave of controversy. As part of the agreement, the British Parliament repealed the Government of Ireland Act 1920 (which had founded Northern Ireland, divided Ireland and asserted territorial right to the whole of Ireland) and the people of the Republic of Ireland amended Articles 2 and 3 of the Irish Constitution, which asserted a territorial right to Northern Ireland. A copy of the agreement was published in every assembly in Northern Ireland and the Republic of Ireland so that people could read before a referendum where they could vote. The agreement called for the creation of an independent commission to review police rules in Northern Ireland, “including ways to promote broad community support” for these agreements. The UK government has also pledged to carry out a “large-scale review” of the criminal justice system in Northern Ireland. 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 peace process has been successful over the past two decades, going beyond the violence of the unrest. Since the conclusion of the Good Friday Agreement in 1998, it has been necessary to pursue a number of other political and legal agreements aimed at consolidating the peace settlement provided for by the VPA. 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. 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.”
