Bill Hunter (1920 – 9 July 2015) was a Trotskyist activist in Britain and a leader of the International Socialist League.
Hunter began his revolutionary career as a member of the Independent Labour Party in World War II, when he was a part of the circle around the Free Expression discussion magazine in that group.
With the decline of the ILP, Hunter became a Trotskyist and joined the Revolutionary Communist Party in which he played a leading role in its final period.
In 1988, he and Martin Ralph led a small split to form the International Socialist League as a section of Moreno's organisation.
[4] Bill Hunter wrote several books, including Forgotten Hero: The Life and Times of Edward Rushton about the blind Liverpool-born anti-slavery campaigner, and the two part autobiography Lifelong Apprenticeship: The Life and Times of a Revolutionary.
