Alexander Puzanov, the Soviet ambassador to Afghanistan, was able to persuade Aslam Watanjar, Sayed Mohammad Gulabzoy and Sherjan Mazdoryar to become part of a conspiracy against Amin. These three men put pressure on Taraki, who by this time believed that "he really was the 'great leader'", to sack Amin from office. It is unknown if Amin knew anything about the conspiracy against him, but it was after the cabinet reorganisation that he talked about his dissatisfaction. On 26 March the PDPA Politburo and the Council of Ministers approved the extension of the powers of the executive branch, and the establishment of the Homeland Higher Defence Council (HHDC) to handle security matters. Many analysts of the day regarded Amin's appointment as Prime Minister as an increase in his powers at the expense of Taraki. However, the reorganisation of the cabinet and the strengthening of Taraki's position as Chairman of the Revolutionary Council, had reduced the authority of the Prime Minister. The Prime Minister was, due to the strengthening of the executive, now appointed by the Chairman of the Revolutionary Council. While Amin could appoint and dismiss new ministers, he needed Taraki's consent to actually do so. Another problem for Amin was that while the Council of Ministers was responsible to the Revolutionary Council and its chairman, individual ministers were only responsible to Taraki. When Amin became Prime Minister, he was responsible for planning, finance and budgetary matters, the conduct of foreign policy, and for order and security. The order and security responsibilities had been taken over by the HHDC, which was chaired by Taraki. While Amin was HHDC Deputy chairman, the majority of HHDC members were members of the anti-Amin faction. For instance, the HHDC membership included Watanjar the Minister of National Defence, Interior Minister Mazdoryar, the President of the Political Affairs of the Armed Forces Mohammad Iqbal, Mohammad Yaqub, the Chief of the General Staff, the Commander of the Afghan Air Force Nazar Mohammad and Assadullah Sarwari the head of ASGA, the Afghan secret police.
