China sacks regional party official Wang Suyi

China's President Xi Jinping has vowed to tackle corruption

China has sacked a top regional party official for suspected "disciplinary violations", state media report.

Wang Suyi was formerly head of Inner Mongolia's United Front Work Department.

The Communist Party's Organisational Department, which is responsible for staffing, confirmed his dismissal on Wednesday, Xinhua news agency reported.

He appears to be the latest in a series of senior officials who have fallen victim to a crackdown on corruption.

Tackling corruption has been President Xi Jinping's most high-profile policy since he became China's leader.

He has warned that "corruption and bribe-taking by some party members and cadres" pose "severe challenges" to the Communist Party's rule.

Mr Wang is suspected of serious disciplinary violations, state-run Xinhua news agency reported, citing a Communist Party official.

The report gave no further details but the term "serious disciplinary violations" is often used to refer to suspected corruption in Chinese reports.

Chinese media have also cited unverified reports that said Mr Wang's mistresses had reported him for corruption of close to 100m yuan ($16.3m; £10.7m) and nepotism.

In recent months, several senior or high-profile officials have been investigated.

Last month, Lei Zhengfu, a former official at the centre of a sex tape extortion scandal, was jailed for accepting bribes.

China's former railways minister, Liu Zhijun, was also put on trial for corruption and abuse of state power.

In May, China announced that it was investigating Liu Tienan, formerly the top official at the body responsible for planning China's economy, for "serious disciplinary violations".

Allegations against Mr Liu first surfaced in December, after an investigative journalist alleged that he made questionable financial deals, fabricated his academic record and threatened to kill a former mistress.
