China will put the ex-police chief at the heart of its biggest political scandal in decades on trial for crimes including defection and taking bribes, state media said on Wednesday, opening a new phase in a case that rattled the Communist Party succession.Wang Lijun fled to a U.S. consulate in south-western China in February, days after his dismissal as police chief of Chongqing, the nearby municipality then run by the ambitious politician Bo Xilai who had raised Wang to prominence as a crime gang-buster.The official Xinhua news agency appeared to end rumours that Wang could be treated lightly for exposing Bo’s misdeeds while inside the consulate, and it laid out the four charges against Wang - defection, taking bribes, bending the law for selfish ends and abusing power.
