Members of Parliament

History

The first member for Aberdare was Charles Stanton, Stanton was a militant miners' agent in the pre-1914 era but had become an equally fierce proponent of the war effort which brought him into conflict with former colleagues including Keir Hardie. Stanton was elected to succeed Hardie as member for Merthyr Boroughs at a by-election in 1915 and comfortably won the Aberdare constituency at the 1918 Coupon Election. By 1922, Stanton's appeal and popularity had faded and he was defeated by George Hall, who held the seat for over twenty years. Labour's hold on Aberdare was never threatened thereafter although Plaid Cymru did make a strong showing at the 1970 general election. Glyn Owen, the new Plaid Cymru candidate in 1974, sustained the campaign from 1970 but this did not seriously threaten the new Labour candidate, Ioan Evans, at the second election that year.
