Former Labour MP, Jon Owen Jones has been named as ChangeUK's lead candidate in Wales for the European elections.
The political party was set up by former Labour and Conservative MPs.
The party wants the UK to remain in the European Union and will campaign for a second referendum.
Mr Jones won Cardiff Central from the Conservatives in 1992 and served as a Labour whip in both opposition and government, before becoming a Welsh Office minister in 1998.
He lost his job a year later when the department was reduced in size following devolution to the Welsh Assembly.
Mr Jones had fallen out of favour with Tony Blair because he backed Rhodri Morgan for Welsh Labour leader against Mr Blair's preferred choice of Alun Michael.
Jon Owen Jones remained an MP until 2005, when he lost his seat to the Liberal Democrats. He then served as chair of the Forestry Commission in Wales, until it was merged into Natural Resources Wales, in a move which he opposed.
