The Congress also set up the political scene for a smooth transition to the fifth generation of party leadership, introducing rising political stars Xi Jinping and Li Keqiang to the Politburo Standing Committee (PSC), the country's "de facto" top decision-making body. Vice-President Zeng Qinghong, an important ally of former General secretary Jiang Zemin, retired from the PSC. Party anti-graft chief Wu Guanzheng, and Legal and Political Commission chief Luo Gan also retired due to age, replaced by He Guoqiang and Zhou Yongkang in their respective posts.
