Direct rule from
Westminster came to an end in Northern Ireland when power was formally devolved to the new
Northern Ireland Assembly, the
North/South Ministerial Council and the
British–Irish Council, as the commencement orders for the British-Irish Agreement came into effect on 2 December 1999. Article 4(2) of the British-Irish Agreement (the Agreement between the British and Irish governments for the implementation of the Belfast Agreement) required the two governments to notify each other in writing of the completion of the requirements for the entry into force of the British-Irish Agreement; entry into force was to be upon the receipt of the later of the two notifications. The British government agreed to participate in a televised ceremony at
Iveagh House in Dublin, the Irish department of foreign affairs.
Peter Mandelson, the
Secretary of State for Northern Ireland, attended early on 2 December 1999. He exchanged notifications with
David Andrews, the Irish foreign minister. Shortly after the ceremony, at 10:30 am, the
Taoiseach, Bertie Ahern, signed the declaration formally amending
Articles 2 and 3 of the Irish Constitution. He then announced to the
Dáil that the British-Irish Agreement had entered into force (including certain supplementary agreements concerning the Belfast Agreement). Speaking at the 1998 commemoration of the
Easter Rising of 1916, Ahern said: The Assembly and Executive were eventually established in December 1999 on the understanding that decommissioning would begin immediately, but were suspended within two months due to lack of progress, before being re-established in May 2000 as Provisional IRA decommissioning eventually began. Aside from the decommissioning issue, ongoing smaller-scale paramilitary activity by the Provisional Irish Republican Army—e.g., arms importations, smuggling, organised crime, punishment beatings, intelligence-gathering and rioting—was also a stumbling block. The loyalist paramilitaries also continued similar activity although as they were not represented by a significant political party, their position was less central to political change. The overall result of these problems was that confidence in the agreement among unionists was damaged. The DUP, the sole anti-agreement party, overtook the pro-agreement UUP in the
2003 Assembly election. The UUP had already resigned from the power-sharing Executive in 2002 following the
Stormontgate scandal, which saw three Sinn Féin members charged with intelligence-gathering. These charges were eventually dropped in 2005 on the controversial grounds that pursuit would not be "in the public interest". One of the three,
Denis Donaldson, was afterwards exposed as a British agent. In 2004, negotiations were held between the two governments, the DUP, and Sinn Féin on an agreement to re-establish the institutions. These talks failed, but a document published by the governments detailing changes to the Belfast Agreement became known as the "
Comprehensive Agreement". On 26 September 2005, it was announced that the Provisional Irish Republican Army had completely decommissioned its arsenal of weapons and "put them beyond use". Nonetheless, many unionists notably the DUP, remained sceptical. Of the loyalist paramilitaries, only the Loyalist Volunteer Force had decommissioned any weapons. Further negotiations took place in October 2006, leading to the
St Andrews Agreement. In May 2007, a power-sharing executive was again established to govern Northern Ireland in devolved matters. The second
Northern Ireland Executive had
Ian Paisley of the DUP as First Minister and
Martin McGuinness of Sinn Féin as deputy First Minister in a
diarchy. Paisley retired from the office of First Minister and from the leadership of the DUP on 5 June 2008 and was succeeded in both functions by
Peter Robinson. In the third Northern Ireland Executive, the same political relationship existed between Robinson and McGuinness as existed formerly between Paisley and McGuinness. After Robinson resigned as First Minister on 11 January 2016, he was replaced by
Arlene Foster. Upon McGuinness's resignation on 9 January 2017, the devolved government in Stormont collapsed, as the Agreement demands when no new leader is appointed. An election was called by Secretary of State for Northern Ireland
James Brokenshire, whereby the DUP and Sinn Féin were returned as the largest parties, and so began a countdown of talks between both leaders before devolved government could be restored. In January 2020, the Executive was re-established. == Comparison to the Sunningdale Agreement==
