Gwynfor Evans propelled Welsh politics onto the UK stage in the second half of the 20th century. This award-winning biography of an iconic figure examines his complex character and dissects his personal and political relationships to reveal, for the first time, what drove Gwynfor Evans. He was one of the rare politicians to have forced Margaret Thatcher to make a U-turn, when he threatened to fast to death in order to ensure the establishment of a Welsh-language TV channel. He also won one of the most famous bi-elections and he is widely credited with paving the way for devolution. In this compelling account of the man known to a generation of Welsh people as, simply, Gwynfor, Rhys Evans exposes the foundations of modern Wales and tells the story of one man and the way he helped mould the devolved UK.
