He worked in a large number of jobs and, at various times, joined the Herald League, the British Socialist Party (BSP), and the Industrial Workers of the World, while still a teenager.
He was soon appointed as national organiser of its associated Young Communist League (YCL), and in 1921 became the youngest member of the party's executive committee.
The following year, he was appointed as the YCL's representative in Moscow, attending the Fourth Congress of the Comintern.
On returning to the UK, he served as editor of the English language edition of Communist International, and then as manager of the Collets Bookshop on Charing Cross Road.
