China's top leadership is expected to discuss how to fill the high-level vacancies left as a result of the nation's anti-graft campaign, according to political scientists and commentators.

They said that apart from discussion of the nation's 13th Five-Year Plan (2016-20), the vacancies and personnel transfers will most likely be on the agenda at next week's leadership meeting.

Former high-profile officials or officers including Zhou Yongkang, Ling Jihua, Guo Boxiong and Xu Caihou have faced or are under corruption charges or disciplinary investigation.
