In June 1956, Molotov was removed as Foreign Minister; on 29 June 1957, he was expelled from the Presidium (Politburo) after a failed attempt to remove Khrushchev as First Secretary. Although Molotov's faction initially won a vote in the Presidium 7–4 to remove Khrushchev, the latter refused to resign unless a Central Committee plenum decided so. In the plenum, which met from 22 to 29 June, Molotov and his faction were defeated. Eventually he was banished, being made ambassador to the Mongolian People's Republic. Molotov and his associates were denounced as "the Anti-Party Group" but notably were not subject to such unpleasant repercussions that had been customary for denounced officials in the Stalin years. In 1960, he was appointed Soviet representative to the International Atomic Energy Agency, which was seen as a partial rehabilitation. However, after the 22nd Party Congress in 1961 during which Khrushchev carried out his de-Stalinisation campaign, including the removal of Stalin's body from Lenin's Mausoleum, Molotov, along with Lazar Kaganovich, was removed from all positions and expelled from the Communist Party. In 1962, all of Molotov's party documents and files were destroyed by the authorities.
