In 1950 "Daily Worker" foreign correspondent Alan Winnington published "I Saw the Truth in Korea", which provided evidence of mass graves containing 1,000s of corpses belonging to civilians executed by South Korean police during the Korean War. In response to Winnington's anti-imperialist views and exposure of war crimes, Clement Attlee's cabinet discussed having Winnington executed by charging him with treason. However, it was instead decided to make him stateless by refusing to renew his passport. Historians and academics have described Winnington as one of the most trustworthy voices of the war.
