Stalin's death on 5 March 1953 prompted major changes in the Soviet leadership. On 15 March 1953, Voroshilov was approved as Chairman of the Presidium of the Supreme Soviet (i.e., the head of state) with Nikita Khrushchev as First Secretary of the Communist Party and Georgy Malenkov as Premier of the Soviet Union. Voroshilov, Malenkov, and Khrushchev brought about the 26 June 1953 arrest of Lavrenty Beria after Stalin's death.
