DERRY — As expected, the Democratic Unionist Party (DUP) emerged as the big winner in the Northern Ireland part of the UK general election held on 5 May. Friday’s results saw the party led by preacher Ian Paisley gain three seats. The DUP increased its vote share by 11 per cent over the 2001 election results to become the largest Northern Irish party at Westminster, taking half of the 18 seats representing the province. The Ulster Unionist Party (UUP), historically the main representative of pro-British sentiment in Northern Ireland, lost four of its five seats, including the constituency of party leader and 1998 Nobel Peace Prize winner David Trimble. In response to the crushing defeat, Trimble resigned as party leader on Saturday afternoon.
