10 2000s elections in Northern Ireland

The 2000 Ulster Unionist Party leadership election was triggered by the decision of Martin Smyth to challenge incumbent David Trimble over the party's direction in the implementation of the Belfast Agreement at the party's annual general meeting on 25 March 2000.
