Communist China’s leader Xi Jinping will secure a third term as party leader at the meeting, upending the succession norms in place since the 1990s. Genuine Communist Party’s historians are reminding that no surprise occur in the fully-controlled organisations such as Chinese Communist Party.

More than 1.5 million officials have been punished, according to data from the party disciplinary body. And the purges have continued for the last few weeks in September.

This final round of purges, masquerading as an anti-corruption campaign, will ensure that Xi will have tighter if not absolute control over personnel and policy issues at the Congress, said Mr Willy Lam, a political analyst at the Chinese University of Hong Kong.

Among purged officials are are former deputy public security minister Mr. Sun Lijun and former justice minister Mr. Fu Zhenghua, who will now spend the rest of their lives behind bars.

Chinese politics expert at the National University of Singapore Mr Wu Muluan concludes that Mr. Xi Jinping has used the anti-corruption campaign to turn the Communist Party "from a collective dictatorship to a personalist dictatorship".
