Sina Weibo had circulated intel that Wang Lequan, a former member of the CCP Politburo had been under investigation for corruption. Once confirmed, this will be the first Politburo level senior official brought down by the Xi-Li administration. It has been a custom and tradition for a new leadership to sacrifice a politburo level senior official to various causes as part of the once a decade power transition. Jiang Zemin took out Chen Xitong. Hu Jintao took out Chen Liangyu. The public had been speculating on which one would be picked this time.
Wang Lequan was the top Party chief in Xinjiang, before named the deputy chief of the Party's politics and law committee.
