The Cultural Revolution was not yet over, and a radical leftist political group known as the Gang of Four, led by Mao's wife Jiang Qing, competed for power within the Party. The Gang saw Deng as their greatest challenge to power. Mao, too, was suspicious that Deng would destroy the positive reputation of the Cultural Revolution, which Mao considered one of his greatest policy initiatives. Beginning in late 1975, Deng was asked to draw up a series of self-criticisms. Although he admitted to having taken an "inappropriate ideological perspective" while dealing with state and party affairs, he was reluctant to admit that his policies were wrong in essence. His antagonism with the Gang of Four became increasingly clear, and Mao seemed to lean in the Gang's favour. Mao refused to accept Deng's self-criticisms and asked the party's Central Committee to "discuss Deng's mistakes thoroughly".
