Sir Anthony Blunt, a distinguished British art historian and curator of the Queen's pictures was exposed as a former Soviet spy in the autumn of 1979. He was stripped of his knighthood and publicly shamed as a traitor for being part of the Cambridge spy ring. Susan Hulme has been speaking to Christopher Morris who was the BBC reporter sent to interview Blunt when the story broke.Photo: Sir Anthony Blunt at the press conference in which he explained his motivation in 1979 (Credit: Aubrey Hart/Getty Images)
