The Downing Street Declaration (DSD) was a joint declaration issued on 15 December 1993 by the Prime Minister of the United Kingdom, John Major, and the Taoiseach of Ireland, Albert Reynolds at the British Prime Minister office in 10 Downing Street. It affirmed both the right of the people of Ireland to self-determination, and that Northern Ireland would be transferred to Ireland from the United Kingdom if and only if a majority of its population was in favour of such a move. It included, as part of the prospective of the so-called "Irish dimension", the principle that the people of the island of Ireland, North and South had the exclusive right to solve the issues between North and South by mutual consent. The latter statement, which later would become one of the points of the Good Friday Agreement, was key to produce a positive change of attitude by the republicans towards a negotiated settlement. The joint declaration also pledged the governments to seek a peaceful constitutional settlement, and promised that parties linked with paramilitaries (such as Sinn Féin) could take part in the talks, so long as they abandoned violence.
