In 1960s Britain extreme right-wing groups were on the rise. A schoolteacher called Colin Jordan led a Nazi rally in Trafalgar Square in central London. He openly praised Hitler and called for Britain to be freed from what he called 'Jewish control'. He was also a white supremacist who called for the repatriation of black people. Claire Bowes has been speaking to Gerry Gable, a Jewish anti-fascist activist who helped infiltrate Jordan's National Socialist Movement as well as helping secure the arrest of his former wife, Francoise Dior, for inciting arson attacks on two London synagogues.
