Under the 1977 Soviet Constitution, the head of government was the leader of the highest executive and administrative organ of state. The head of government was appointed by and accountable to the Supreme Soviet (and its Presidium).[4] The head of government was tasked with resolving all state administrative duties within the jurisdiction of the USSR to the degree which were not the responsibility of the Supreme Soviet or its Presidium. The head of government managed the national economy, formulated the five-year plans and ensured socio-cultural development.[5] It functioned as the most influential office of government and nominally the most influential office until the establishment of the Office of the President of the Soviet Union in 1990.
Vladimir Lenin and Joseph Stalin died in office of natural causes, and three premiers resigned—Alexei Kosygin, Nikolai Tikhonov and Ivan Silayev. Another three were concurrently party leader and head of government (Lenin, Stalin and Nikita Khrushchev). The one who spent the shortest time in office was Ivan Silayev, at 119 days. Kosygin spent the longest time in office—16 years.
^On August 19, 1991, due to the illness of Valentin Pavlov, the duties of the head of the government of the USSR were assigned to First Deputy Prime Minister Vitaly Doguzhiyev.
