China's national political advisory body is no harbor for corrupt officials, its spokesman said?Monday ahead of?its annual session.

The National Committee of the Chinese People's Political Consultative Conference (CPPCC) fully supports the investigation into those corrupt officials who have violated rules and might break the law, spokesman Lyu Xinhua said at a press conference.

Two vice chairmen of the CPPCC National Committee, Ling Jihua and Su Rong, have been suspected of corruption and investigated accordingly.

Su is being investigated by the Supreme People's Procuratorate over allegations of accepting huge bribes for promoting his inferiors, among others.

A CPPCC meeting on Saturday removed Ling from the post of National Committee vice chairman and also stripped him of the CPPCC membership.

Although most of their violations did not occur during their tenure as leading national political advisors, the cases have affected the image of the CPPCC, Lyu said.

The CPPCC would upgrade integrity overhaul and anti-corruption measures, he said.

"The anti-corruption campaign is what honest members of the Communist Party of China and the general public welcome and support, with which a victory would be achieved," he said.

The annual session of the CPPCC National Committee is scheduled to open on Tuesday.
