The Blair Government introduces legislation into the Parliament of the United Kingdom to facilitate a power-sharing agreement in Northern Ireland between Ian Paisley's Democratic Unionist Party and Sinn Fin.
- Sinn Fin leader Gerry Adams recommends that Sinn Fin support a British-Irish power-sharing plan for Northern Ireland that involves the public decommissioning of the arms held by the Irish Republican Army. Ian Paisley of the loyalist Democratic Unionist Party may become first minister of Northern Ireland, with former IRA member Martin McGuinness as his deputy.
- DUP leader and Northern Ireland First Minister Peter Robinson dismisses calls from Sinn Fin for a Scotland-style referendum on independence for Northern Ireland, telling his party's annual conference that a majority of Catholics want Northern Ireland to stay part of the United Kingdom.
- First Minister of Northern Ireland Ian Paisley announces his intentions to stand down from the post in May 2008 and, at the same time, resign as leader of the DUP, a party he has led for almost 40 years.
- Home rule returns to Northern Ireland. DUP leader Ian Paisley and Sinn Fein's Martin McGuinness take office as First Minister and Deputy First Minister, respectively.
- The anti-Good Friday Agreement Democratic Unionist Party with 30 seats becomes the biggest party in Northern Ireland in the Northern Ireland Assembly Election, 2003, replacing the Ulster Unionist Party (27 seats), while Sinn Fin at 24 seats replaces the SDLP (18 seats) as the major Irish nationalist party.
