CCTV said among the opening headlines of its main evening news bulletin that Wan died in Beijing.
Wan was classed by some analysts as one of Communist China's so-called Eight Immortals, a reference to a group of elite, elderly revolutionaries who survived the purges of Maoism and backed the ascent of Deng Xiaoping -- one of their number -- to power.
He was chairman of the rubber stamp legislature National People's Congress (NPC) for five years from 1988, a tumultuous time that saw the bloody crackdown on pro-democracy protestors at Tiananmen Square in Beijing in June 1989.
Online Chinese news outlet The Paper reported that Wan died of illness on Wednesday afternoon, citing his son.

A fine tennis player and known for an affable personality, Wan was close to Zhao Ziyang, the Communist Party general secretary who was ousted after opposing the use of force to clear Tiananmen Square of protesters. Zhao died in 2005.
Wan's successor as NPC chairman, Qiao Shi, died last month. He was 91.
