Xu Caihou, former Vice Chairman of China's Central Military Commission (CMC), has confessed to taking bribes, military prosecutors announced on October 28.

The investigation into Xu's case has concluded and the filing of the case has begun, said a statement from the military procuratorate.

Xu was found to have taken advantage of his position to assist the promotions of others, accepting huge bribes personally as well as through his family, and to have sought profits for others in exchange for bribes. The amount of the bribes was "extremely large," the statement said.

The Communist Party of China Central Committee decided to expel Xu from the Party and hand his case to prosecutors at a meeting in June. Xu had been under investigation since March.

Xu, 71, was CMC vice chairman from 2004 to 2012 and was made a general in 1999. He has been discharged from military service with his rank revoked.

Xu was diagnosed with bladder cancer in February 2013 and is still undergoing treatment, a statement on the Ministry of National Defense website said on Tuesday.
