Peng had been an alternate member of the Central Committee since 1934, a full member since 1938, and a member of the Politburo since 1945, but it was not until he became the leader of the PLA and moved permanently to Beijing in November 1953 that he could attend regular political meetings and became active in domestic politics. Peng had been loyal to Mao's leadership since the 1935 Zunyi Conference and continued to support Mao for several years after he had moved to Beijing. Peng, like Lin Biao, was implicated in passively supporting Gao Gang's effort to replace Liu Shaoqi as the second most powerful person in China in 1953 but then opposed Gao in 1954 once Mao had made his own opposition clear. Mao did not take any action against Peng or Lin, but Peng's involvement alienated Peng from Liu and Liu's supporters.
