When former Chongqing municipality police chief Wang Lijun confessed to taking bribes and covering up the murder of British businessman Neil Heywood, he may have signed the death warrant for Communist Party star Bo Xilai's career.

Bo's wife has been convicted of poisoning Heywood over an extortion attempt, and Wang was reportedly pressured by Bo after he began his investigation into the murder, eventually fleeing briefly to a US consulate.

The Wang affair exposed the conspiracies and luxurious lifestyle of China's ruling class and forced the Communist Party to suspend Bo, once considered a rising star.
