Xu Caihou
In March 2014, state media publicly announced Gu's corruption investigation. Gu was charged with corruption, bribery, embezzlement and abuse of power by the PLA Military Procuratorate. His case was then moved to court martial. Gu was the highest-ranked military official to be charged with corruption since the Wang Shouye scandal in 2006. Chinese-language media also reported that during the investigation, Gu gave evidence against Xu Caihou, alleging that Xu offered promotions in exchange for money. Soon after, Xu became subject to his own corruption probe, and on June 30, Xu was expelled from the Communist Party of China.
