Peter was a Christian Socialist as a youth, then a member of the Communist Party until the Soviet invasion of Hungary in 1956. Leaving the CP, Peter became a founding activist of what became the New Left in Britain – first within the Socialist Review Group, then the International Socialism Group.
A Marxist for most of his adult life, Peter, in his final years at least, is probably best described as a non-dogmatic revolutionary Socialist – drawing on Anarchist as well as Marxist sources in his later works.
