From the longer English Wikipedia page [1]

Georgy Maximilianovich Malenkov (Russian: Гео́ргий Максимилиа́нович Маленко́в; 8 January 1902 [O.S. 26 December 1901] – 14 January 1988) was a Soviet politician and Communist Party leader.

Malenkov was forced to resign, in February 1955, after he came under attack for abuse of power and his close connection to Lavrentiy Beria (who was executed as a traitor in December 1953). He was held responsible for the slow pace of reforms, particularly when it came to rehabilitating political prisoners.

For two more years, Malenkov remained a regular member of the Presidium. Together with Nikita Khrushchev, he flew to the island of Brioni (Brijuni, Yugoslavia) on the night of 1–2 November 1956 to inform Josip Broz Tito of the impending Soviet invasion of Hungary scheduled for 4 November

On Stalin’s death in 1953, Malenkov was briefly party leader, but was soon replaced by Nikita Khrushchev, with Malenkov as premier, as the party did not want both functions entrusted to the same person. His two-year term ended in failure. He was expelled from the Politburo in 1957. In 1961 he was expelled from the party and exiled to Kazakhstan.
