Tony Cliff was a Palestinian Jew who became a revolutionary socialist in his teens. He came to Britain in the 1940s and built the anti-Stalinist left, pulling together the group that was to become the Socialist Workers Party. He died in 2000 aged 82 and thousands attended his funeral procession through Golders Green. This lovingly crafted book is the culmination of years of work, drawing on interviews with over 100 people who knew Cliff and painstaking research in archives around the country. It is a majestic example of political biography at its best.
