2016 Ogmore by-election

On 5 May 2016, a by-election was held in the UK Parliamentary constituency of Ogmore. It was triggered by the resignation of the incumbent Huw Irranca-Davies following his decision to contest the coterminous Ogmore constituency in the 2016 Welsh Assembly election.

Chris Elmore of the Labour Party won the by-election with 52.6 per cent of the vote.

The by-election was held on the same day as the Welsh Assembly election, as well as elections for the Scottish Parliament, the Northern Ireland Assembly, for the Mayor and Assembly of London and in numerous local authorities in England. A by-election for Sheffield Brightside and Hillsborough was also held on the same day.

Background
The seat fell vacant after the incumbent MP, Huw Irranca-Davies of the Labour Party, chose to resign following his selection to contest the coterminous Ogmore constituency in the Welsh Assembly election. On 23 March 2016, Irranca-Davies was appointed Crown Steward and Bailiff of the Manor of Northstead the process by which resignations from the House of Commons are permitted. Irranca-Davies had been the MP for the seat since a previous by-election in 2002. Irranca-Davies had originally announced that he would seek Labour's nomination for the Welsh Assembly's Ogmore in October 2015, stating that if he was selected he would resign his Westminster seat. Irranca-Davies successfully contested his Assembly election. Irranca-Davies was not obliged to resign upon his nomination, though following the Wales Act 2014, which came into effect during the 2016 Assembly election, he would have had to resign his Westminster seat following his Assembly victory. Given that in both the Assembly and Westminster Ogmore was considered a safe seat for Labour his early resignation allowed the by-election to be held on the same day rather than forcing voters to go to the polls again a few weeks later.
