The 17th Central Politburo of the Chinese Communist Party was elected by the 17th Central Committee of the Chinese Communist Party on October 22, 2007. Eventually, four members of this Politburo were expelled from the Communist Party for not adhering to the leading party thought. They were, in order of the time of expulsion, Bo Xilai, Xu Caihou, Zhou Yongkang, and Guo Boxiong. This politburo was preceded by the 16th Politburo of the Chinese Communist Party and succeeded by the 18th Politburo of the Chinese Communist Party.
