2006 Blaenau Gwent by-elections
By-elections for both the United Kingdom parliamentary and Welsh assembly constituencies of Blaenau Gwent were held on 29 June 2006, triggered by death of incumbent independent Member of Parliament (MP) and Assembly Member (AM) Peter Law on 25 April 2006. Law's successors won both seats: Dai Davies—Law's former election agent—won the UK parliamentary by-election as an independent with support from the Blaenau Gwent People's Voice (BGPV); meanwhile, Trish Law—Peter's widow—who also ran as an independent on a BGPV ticket, won her husband's former seat in the Welsh Assembly.
Law denied the Labour Party a victory in the AM by-election which would have restored their majority in the Welsh Assembly; they lost it when her husband was expelled from the party.
Davies was the first independent to hold a seat previously occupied by another independent in a by-election since Sir Charles Townshend won the November 1920 The Wrekin by-election. The by-elections were held on the same day 2006 Bromley and Chislehurst by-election.
