The most senior surviving member of Cambodia’s Khmer Rouge regime has appeared in court for the first time. Nuon Chea, who was second-in-command to Pol Pot, asked for a postponement to his appeal hearing because of a row over his legal team. Nuon Chea is one of five senior Khmer Rouge officials to be arrested and charged by a special genocide tribunal. More than a million people are thought to have died during the Khmer Rouge rule between 1975 and 1979. Researchers say Nuon Chea was the ideological driving force behind the regime, responsible for its most radical policies. (BBC)
