Chen Liangyu
Under Secretary Wu Guanzheng, the CCDI established its first central inspection teams in August 2003. These teams, led by retired ministerial-level officials and reporting to the CCDI rather than local party committees, were empowered to initiate investigations, conduct interviews and review relevant documents. The opinion of a central inspection team was an important factor in determining whether or not an official was disciplined, and the teams played an important role in the expulsion of Shanghai party chief (and Politburo member) Chen Liangyu from the party because of corruption.
