The Presidium of the National People's Congress of the People's Republic of China is a 178-member body of the National People's Congress (NPC). It is composed of senior officials of the Communist Party of China (CPC), the state, non-Communist parties and All-China Federation of Industry and Commerce, those without party affiliation, heads of central government agencies and people's organizations, leading members of all the 35 delegations to the NPC session including those from Hong Kong, Macao, Taiwan and the People's Liberation Army. It nominates the President and Vice President of China, the Chairman, Vice-Chairman, and Secretary-General of the Standing Committee of the NPC, the Chairman of the Central Military Commission, and the President of the Supreme People's Court for election by the NPC. Its functions are defined in the Organic Law of the NPC, but not how it is composed. In practice, the Standing Committee of the National People's Congress drafts a list of candidates, then presides over a preparatory meeting of the NPC that revises and approves the list. After the Presidium has been elected, it presides over the rest of the NPC session..
