BEIJING, June 15 -- A former senior official and a former senior executive of a major state-owned enterprise have been expelled from the Communist Party of China (CPC) for "serious violations of discipline and the law," said China's top anti-graft body on Monday.

The Central Commission for Discipline Inspection said in a statement that Sun Hongzhi, vice minister of the State Administration for Industry &Commerce, and Liao Yongyuan, former general manager with China National Petroleum Corporation, have been expelled from CPC following graft investigations.

It accused the two of accepting a huge amount of bribes, seeking profits for others and committing adultery.

As senior leading cadres of the CPC, Sun and Liao seriously violated Party rules and organizational discipline, said the statement, adding that they also broke the law and "showed no restraint even after the 18th CPC National Congress" in 2012 when an upgraded anti-corruption campaign was started.

The penalties were imposed according to Party regulations. The two were also dismissed from their public posts with State Council approval while their cases will be transferred to prosecutors.
