The Belfast Agreement is also known as the Good Friday Agreement, as it was concluded on Good Friday on 10 April 1998. It was an agreement between the British and Irish governments and most of northern Ireland`s political parties on how to govern Northern Ireland. Discussions that led to the agreement have focused on issues that have led to conflict in recent decades. The aim was to form a new de-defyed government for Northern Ireland, where unionists and nationalists would share power. The main themes addressed by Sunningdale and dealt with in the Belfast Agreement are the principle of self-determination, the recognition of the two national identities, intergovernmental cooperation between the British and Ireland and legal procedures for compulsory power-sharing, such as inter-community voting and the D`Hondt system for appointing ministers to the executive.   Former IRA member and journalist Tommy McKearney says the main difference is the British government`s intention to negotiate a comprehensive agreement including the IRA and the most intransigent unionists.  With regard to the right to self-determination, two qualifications are recorded by the writer Austen Morgan. First, the transfer of territory from one state to another must be done through an international agreement between the British and Irish governments. Second, the population of Northern Ireland can no longer be alone in united Ireland; They need not only the Irish government, but also the people of their neighbouring country, Ireland, to support unity. Mr Morgan also pointed out that, unlike the Irish Act 1949 and the Northern Ireland Constitution Act 1973, drawn up under Sunningdale, the 1998 agreement and the resulting British legislation explicitly provide for the possibility of a unified Ireland.  The agreement contains a complex set of provisions in a number of areas, of which: the agreement consists of two related documents, both agreed on Good Friday, Friday 10 April 1998 in Belfast: the agreement was for Northern Ireland to be part of the United Kingdom and remain in place until the majority of the population of Northern Ireland and the Republic of Northern Ireland wanted otherwise.
