WUHAN -?A senior judge in Central China's Hubei province has been sacked over his extramarital affair, the Hubei Provincial Higher People's Court said Friday.

Zhang Jun, head of the court's third division of criminal cases, was stripped of his Communist Party of China (CPC) membership and removed from his official post, according to the court.

Investigation against Zhang was launched by the court and the provincial CPC discipline inspection authority after an online video footage exposed his affair.

Zhang has maintained the improper relations for a long time and violated Party discipline, said the court.

The seventh Session of the Standing Committee of the 12th Hubei Provincial People's Congress, the provincial legislature, agreed on Thursday to remove Zhang from his post according to law.
