Chen Xitong
As the leader of "Beijing clique", Chen challenged Jiang Zemin's newly obtained authority during his presidency. This led to Chen's downfall in 1995 during an anti-corruption campaign led by Jiang's Shanghai clique. Some observers view Chen's downfall as a political struggle between Chen and Jiang. According to the book "Conversations with Chen Xitong", he denied the corruption charges brought against him, calling them "the worst miscarriage of justice involving a high-level leader since the Cultural Revolution, or since 1989... an absurd miscarriage of justice."
