Caerwyn Roderick
Appearance
Caerwyn Eifion Roderick (born 15 July 1927) was British Labour Party Member of Parliament (MP) for Brecon and Radnor from 1970 to 1979, when he lost to the Conservative candidate Tom Hooson. There has been no Labour MP for the seat (since renamed Brecon and Radnorshire) since then, as the Liberal Democrats are now the main challengers to the Conservatives.
