Zhang Huawei, a former disciplinary officer at the vice-minister level has been expelled from the Communist Party of China over graft issues and serious violations of the Party's code of conduct, the Central Commission for Discipline Inspection said on Wednesday.

The top anti-graft watchdog will also cancel Zhang's retirement benefits and confiscate his illegal gains, the CCDI said in a statement on its website on Wednesday.

Zhang, a former inspector with central inspection teams, was found to have seriously violated political discipline and used his position to interfere with the work of institutions being inspected, the watchdog said. He also resisted the Party's investigation, it said.
