Hua's unimaginative policies received relatively little support, and he was regarded as an unremarkable leader, lacking political support within the Politburo. At the time Deng Xiaoping was still living in seclusion because of "political mistakes," and the issue of his return to politics was yet again put on the table. Deng had insisted on supporting all of Hua's policies in one of the letters the two men exchanged, to which Hua responded that Deng had "made mistakes, and rightfully must continue to receive criticism." The arrest of the Gang of Four, Hua said, did not justify that Deng's "revisionist" ideas should resurface. During a Politburo meeting in March 1977, many members voiced support for Deng's return, to no avail. In a letter to Hua dated April 10, Deng Xiaoping wrote, "I am fully behind Chairman Hua's policies and agenda for the country." This letter would be openly discussed in the Politburo, and in July 1977, Deng Xiaoping was restored in his former posts. In August, the 11th Party Congress was held, which again rehabilitated Deng and confirmed his election as the new Committee Vice-Chairman, and the Central Military Commission's Vice-Chairman, Deng guaranteed the elevation of his supporters, Hu Yaobang, Zhao Ziyang and Wan Li.
