陈希同
In October 1992, at the 14th Party Congress, Wei was named to the Politburo, in addition to becoming a Secretary of Central Secretariat, and the Secretary of Central Commission for Discipline Inspection (CCDI). During Wei's term as CCDI chief, some 680,000 disciplinary cases were processed. The most prominent case was that against Beijing party chief Chen Xitong, who was investigated for corruption beginning in July 1994 and expelled from the party a month later. In the wake of Chen's disgrace Wei himself took over at Beijing party chief and stayed in the position for two years. In 1993, he also became Chairman of the All-China Federation of Trade Unions and served for two terms. At the 15th Party Congress held in 1997, Wei earned a seat on the elite seven-man Politburo Standing Committee and continued to serve as CCDI Secretary.
