negotiations began in 1994 in Northern Ireland, without Sinn Féin. The Provisional IRA declared a ceasefire in August 1994. Sinn Féin then joined the talks, but the Conservative government under John Major soon came to depend on unionist votes to remain in power. It suspended Sinn Féin from the talks, and began to insist that the IRA decommission all of their weapons before Sinn Féin be re-admitted to the talks; this led to the IRA calling off its ceasefire. The new Labour government of Tony Blair was not reliant on unionist votes and re-admitted Sinn Féin, leading to another, permanent, ceasefire. The talks led to the Good Friday Agreement of 10 April 1998, which set up an inclusive devolved government in Northern Ireland, and altered the Dublin government's constitutional claim to the whole island in Articles 2 and 3 of the Constitution of Ireland. Republicans opposed to the direction taken by Sinn Féin in the peace process formed the 32 County Sovereignty Movement in the late 1990s. 1998–2017 At the 1997 Irish general election, Caoimhghín Ó Caoláin was elected to the Dáil. In doing so, he became the first person under the "Sinn Féin" banner to be elected to Leinster House since 1957, and the first since 1922 to take their seat. Ó Caoláin's entry to the Dáil marked the beginning of a continuous Sinn Féin presence in the Republic of Ireland's national political bodies. The party expelled Denis Donaldson, a party official, in December 2005, with him stating publicly that he had been in the employ of the British government as an agent since the 1980s. Donaldson told reporters that the British security agencies who employed him were behind the collapse of the Assembly and set up Sinn Féin to take the blame for it, a claim disputed by the British government. Donaldson was found fatally shot in his home in County Donegal on 4 April 2006, and a murder inquiry was launched. In April 2009, the Real IRA released a statement taking responsibility for the killing. When Sinn Féin and the Democratic Unionist Party (DUP) became the largest parties, by the terms of the Good Friday Agreement no deal could be made without the support of both parties. They nearly reached a deal in November 2004, but the DUP insisted on photographic and/or video evidence that decommissioning of IRA weapons had been carried out, which was unacceptable to
