Under the current PRC Constitution, the presidency is a largely ceremonial office with limited power.[2] However, since 1993, as a matter of convention, the presidency has been held simultaneously by the General Secretary of the Chinese Communist Party, the top leader in the one party system. The presidency is officially regarded as an institution of the state rather than an administrative post; theoretically, the president serves at the pleasure of the National People's Congress (NPC), the legislature, and is not legally vested to take executive action on his own prerogative.[note 1] The current president is Xi Jinping, who took office in March 2013.
