Y Lolfa Gwynfor Evans

As one of the rare politicians to have forced Margaret Thatcher to make a U-turn when he threatened a hunger strike to campaign for a Welsh language TV channel, and as the winner of one of the most famous by-elections, Gwynfor Evans propelled Welsh politics onto the UK stage. His leadership of the Welsh resistance against the flooding of Welsh valleys gained it UK-wide publicity, and he is credited with paving the way for our post-devolution UK-politics.
