A biography of the intriguing life of the unknown Liberal British Prime Minister.

Roy Hattersley was in the Wilson and Callaghan cabinets, and rose to be the former deputy leader of the Labour Party as well as Shadow Home Secretary and Shadow Chancellor of the Exchequer. Since retiring from front-bench politics and going to the House of Lords he has been a full-time writer, producing regular newspaper articles including a column in the Guardian as well as a series of books, the latest of which is The Edwardians. He believes that the almost forgotten Campbell-Bannerman was in reality one of the most significant of all Prime Ministers, and is glad of this chance to show his real significance.
