The Member of Parliament for Ogmore in Bridgend County Borough, Sir Raymond Powell, of the Labour Party died on 7 December 2001.
The by-election to fill the seat was held on 14 February 2002. Labour faced no realistic challenge in this very safe seat and retained it easily, with only Plaid Cymru making progress from their 2001 result. The Socialist Labour Party, who had not previously stood, achieved a good result for a minor party and retained their deposit.
