Sun Huaishan, a former senior political advisor, was expelled from the Communist Party of China (CPC) and dismissed from public office for violating the Party's code of conduct and corruption.
The CPC Central Commission for Discipline Inspection (CCDI) said in a statement Friday that an investigation found that Sun had "severely violated political discipline and rules."
Sun was formerly a member of the Standing Committee of the Chinese People's Political Consultative Conference (CPPCC) National Committee and head of the Committee for Hong Kong, Macao and Taiwan Compatriots and Overseas Chinese of the CPPCC National Committee.
The CCDI statement said Sun had spoken inappropriately of the Party's key policies, formed cliques and obstructed the investigation into him.
He was found to have attended banquets paid for with public funds and asked other organizations to sponsor holidays for his relatives with public spending, acts that violate the Party's "eight-point" frugality code, the statement said.
The statement also accused Sun of accepting money and gifts and abusing his power and influence to seek benefits for his son's business operations.
Also, he took advantage of his posts to seek benefits for others and accepted cash or gifts in return.
The statement said Sun, as a member of the CPC Central Committee, was "politically disloyal" to the Party and greedy.
The qualification of Sun as a delegate to the 18th CPC National Congress will also be terminated and his ill gotten gains will be confiscated, the statement said.
The case will be transferred to judicial organs.
The statement said the decision to expel Sun from the CPC will be confirmed at a plenary meeting of the CPC Central Committee.
