The 43 Group was an anti-fascist organisation formed in the wake of WWII by Jewish ex-servicemen and women, in response to the return of the fascist followers of Oswald Mosley to the streets of Britain. Between 1946-50 the 43 Group waged a direct and often violent street campaign against the fascists, with Ridley Road, Dalston as the most prominent and violent battleground. Hear historian Daniel Sonabend tell its story.
