Four judges and a State-owned company executive in Shanghai embroiled in a prostitution scandal have been expelled from the Party, with four of them also given 10 days' administrative detention by police.

The penalties imposed by the Commission for Discipline Inspection of the CPC Shanghai Committee and announced on Tuesday come five days after an anonymous blogger posted video clips of a group of officials from Shanghai High People's Court visiting karaoke clubs, alleging that they patronized prostitutes.

The commission said that Chen Xueming, chief judge of the No 1 Civil Tribunal at Shanghai High People's Court, and Zhao Minghua, deputy chief judge of the same tribunal, had been expelled from the Party. The high court will submit an appeal to the city's people's congress for them to be removed from their positions as judges and public servants.
