Karmal still had support within the party, and used his base to curb Najibullah's powers. He began spreading rumors that he would be reappointed General Secretary. Najibullah's power base was in the KHAD, the Afghan equivalent to the KGB, and not the party. Considering the fact that the Soviet Union had supported Karmal for over six years, the Soviet leadership wanted to ease him out of power gradually. Yuli Vorontsov, the Soviet ambassador to Afghanistan, told Najibullah to begin undermining Karmal's power slowly. Najibullah complained to the Soviet leadership that Karmal used most of his spare time looking for errors and "speaking against the National Reconciliation ". At a meeting of the Soviet Politburo on 13 November 1986 it was decided that Najibullah should remove Karmal; this motion was supported by Gromyko, Vorontsov, Eduard Shevardnadze, Anatoly Dobrynin and Viktor Chebrikov. A PDPA meeting in November relieved Karmal of his Revolutionary Council chairmanship, and exiled him to Moscow where he was given a state-owned apartment and a dacha. Karmal was succeeded as Revolutionary Council chairman by Haji Mohammad Chamkani, who was not a member of the PDPA.
