List of by-elections to the Senedd (original) (raw)

This is a list of by-elections to the Senedd (Welsh Parliament; Welsh: Senedd Cymru; formerly known as the National Assembly for Wales). Where seats changed political party at the by-election, the result is highlighted. *Peter Law left the Labour Party and sat as an independent prior to his death. The by-election was won by his widow, but is classed as an independent gain from Labour.
