Council of Ministers of the Soviet Union
Premier Nikolai Bulganin, chairman of the Council of Ministers of the Soviet Union and then an ally of Khrushchev, called the session to order and immediately yielded the floor to Khrushchev, who began his speech shortly after midnight on 25 February. For the next four hours, Khrushchev delivered "On the Cult of Personality and Its Consequences" before stunned delegates. Several people became ill during the tense report and had to be removed from the hall.
