A former top Chinese Communist Party official who was once tipped for a top leadership post was sentenced to life in prison for bribery, Chinese state media said today, the latest senior cadre to fall in President Xi Jinping’s sweeping anti-corruption crusade. Sun Zhengcai, a former Politburo member and party chief of the southwestern mega-city of Chongqing, was found guilty of taking over 170 million yuan ($26.7 million) in bribes, the official Xinhua news service said, adding that his “illegal gains” would be confiscated.
