As his replacement, Mao Zedong, who had been the de facto leader of the party since the Long March, was named as Chairman of the Politburo of the CCP Central Committee (Chinese: 中国共产党中央政治局主席). The seventh CCP National Congress introduced the post of Chairman of the Central Committee into the party constitution, and in 1956 the General Secretary was given the day-to-day management of the Party Secretariat. The chairman was elected by the Central Committee in plenary session and had full powers over the Central Committee, the Politburo and its Standing Committee.
