Lavrentiy Beria, head of MVD, is arrested by Nikita Khrushchev and other members of the Politburo.

Lavrentiy Pavlovich Beria was a Soviet politician and one of the longest-serving and most influential of Joseph Stalin's secret police chiefs, serving as head of the NKVD from 1938 to 1946, during the country's involvement in the Second World War.

The Ministry of Internal Affairs of the USSR was the interior ministry of the Soviet Union from 1946 to 1991. The MVD was established as the successor to the NKVD during the reform of the People's Commissariats into the Ministries of the Soviet Union in 1946 as part of a broader restructuring of the government. The MVD did not include agencies concerned with secret policing unlike the NKVD, with the function being assigned to the Ministry of State Security (MGB), which had been established during the Second World War. The MVD and MGB were briefly merged into a single ministry from March 1953 until the MGB was split off as the Committee for State Security (KGB) in March 1954.

Nikita Sergeyevich Khrushchev was the First Secretary of the Communist Party of the Soviet Union from 1953 to 1964 and the Chairman of the Council of Ministers (premier) from 1958 to 1964. As leader, he stunned the communist world by denouncing his predecessor Joseph Stalin and launching a campaign of de-Stalinization, and presided over the Cuban Missile Crisis in 1962.

A politburo or political bureau is the highest organ of the central committee in communist parties. The term is also sometimes used to refer to similar organs in socialist and Islamist parties, such as the Political Bureau of Hamas. Politburos are part of the governing structure in most former and existing communist states.
