The establishment of the BIIGC was provided for under Strand Three of the Good Friday Agreement, signed on 8 March 1998. The inaugural meeting took place at
10 Downing Street on 17 December 1999 and was chaired by Prime Minister
Tony Blair and
Taoiseach Bertie Ahern and attended by representatives of the
Irish government, the
British government and the
Northern Ireland Executive. The BIIGC replaced the Anglo-Irish Conference which was established under Article 2 of the
Anglo-Irish Agreement of 1985. Under the terms of the
Belfast Agreement, the BIIGC is supported by officials of the British and Irish Governments, including a standing Joint Secretariat of officials dealing with non-devolved Northern Ireland matters. The BIIGC secretariat has approximately 21 staff (10 for the British side, 11 for the Irish side). The staff comprise a mix of grades from senior civil servants to administrative support grades. ==Devolved matters==
