Since 2018, the main body of the Chinese constitution declares that "the defining feature of socialism with Chinese characteristics is the leadership of the Chinese Communist Party (CCP)." The 2018 amendments constitutionalized the ''de facto'' one-party state status of China, wherein the CCP General Secretary (party leader) holds ultimate power and authority over state and government and serves as the informal Paramount leader. The current General Secretary is Xi Jinping, who took office on November 15, 2012, and was re-elected on 25 October 2017. The electoral system is pyramidal. Local People's Congresses are directly elected, and higher levels of People's Congresses up to the National People's Congress (NPC) are indirectly elected by the People's Congress of the level immediately below. Another eight political parties, have representatives in the NPC and the Chinese People's Political Consultative Conference (CPPCC). China supports the Leninist principle of "democratic centralism", but critics describe the elected National People's Congress as a "rubber stamp" body.
