Blaenau Gwent by-elections, 2006

Two by-elections were held for the constituency of Blaenau Gwent in Wales following the death of Member of Parliament and Assembly Member Peter Law on 25 April 2006. As Law was the MP and Assembly Member (AM), his death required by-elections in both the parliamentary seat and the equivalent Welsh Assembly constituency. The two elections polled on the same day, 29 June, as a by-election in Bromley and Chislehurst. A win by the Labour Party in the AM by-election would have restored their majority in the Welsh Assembly, which was lost when Law was expelled from the party.

Law's successors won both seats: the independent Dai Davies won the Westminster seat with a majority of about two and a half thousand. He was the first independent to hold a seat previously occupied by an independent since Sir Charles Vere Ferrers Townshend held The Wrekin in 1920.

The writ for the UK Parliament by-election was moved on 6 June so that it would be held on the same date as the Assembly by-election, (29 June 2006). Labour whips had reportedly pressed for the election to be held on 25 May. The movement of the writ was more complicated because Law sat as an Independent, and therefore the convention that the party of the former member moves the writ cannot apply. According to the precedent (when Denis Canavan resigned his Parliamentary seat at Westminster as an Independent), the whip of the governing party moves the writ.
