Guangdong’s No 2 graft-buster is under investigation for alleged breaches of Communist Party discipline, the party’s watchdog announced on Wednesday afternoon. The Central Commission for Discipline Inspection said Zhong Shijian, the deputy chief of the commission’s Guangdong branch, was accused of severely violating party discipline and law, a term that usually refers to corruption. Zhong, 59, is also the head of Guangdong Department of Supervision and has close ties with former top provincial political adviser Zhu Mingguo. A source close to the provincial discipline commission said Zhong was taken away from his office on Monday at around noon. But the commission refused to comment on Zhong’s case when contacted on Tuesday. Hours before the official announcement on Wednesday night, Zhong’s name had been removed from the official website of the Guangdong anti-graft watchdog. Zhong was born in Dianbai, a county-level city under Maoming, in Guangdong. He began his political career in 1990 as deputy chief of Wanshan district in Zhuhai and went on to become the city’s mayor in 2007. Zhong was promoted to deputy party secretary of the Guangdong anti-graft watchdog in 2012, serving under Zhu, the party secretary. In February, Zhu was expelled from the party and deposed as chairman of the Guangdong political advisory body for allegedly taking huge bribes and violating the birth control policy.
