GUIYANG - A former political advisor in southwest China's Guizhou Province has been expelled from the Communist Party of China (CPC) and public office for serious discipline violations, the CPC's anti-graft authority announced Thursday.

Investigation found that Cheng Mengren, former deputy director of the Guizhou Provincial Department of Transport, had exacted profits for others and taken a great amount of bribes and gifts himself or through the hands of his mistress, according to the CPC's provincial discipline inspection commission.

Authorities are handling his case according to procedure and have passed the case to judiciary organizations, according to the commission.

Cheng became deputy director of the provincial transport department in March 2007. He was removed from the post in November 2012 before being named deputy director of the proposal committee of the Guizhou Provincial Committee of Chinese People's Political Consultative Conference.
