Government of the Soviet Union
The government was led by a chairman, most commonly referred to as "premier" by outside observers. The chairman was nominated by the Central Committee of the Communist Party of the Soviet Union (CPSU) and elected by delegates at the first plenary session of a newly elected Supreme Soviet of the Soviet Union. Certain governments, such as Ryzhkov's Second Government, had more than 100 government ministers, serving as first deputy premiers, deputy premiers, government ministers or heads of state committees/commissions; they were chosen by the premier and confirmed by the Supreme Soviet. The Government of the Soviet Union exercised its executive powers in conformity with the constitution of the Soviet Union and legislation enacted by the Supreme Soviet. The first government was led by Vladimir Lenin, and the last government was led by Valentin Pavlov. The appointment of Ivan Silayev, commonly viewed as the last Soviet head of government, by the Russian Soviet Federative Socialist Republic (Russian SFSR) was in breach of the Soviet constitution.
