 Secret police became a part of MVD after Lavrenty Beria merged the MGB into the MVD in March 1953.Within a year Beria's downfall caused the MVD to be split up again; after that, the MVD retained its "internal security" (police) functions, while the new KGB took on "state security" (secret police) functions.In his efforts to fight bureaucracy and maintain 'Leninist principles', Nikita Khrushchev, as the Premier of the Union, called for the dismissal of the All-Union MVD.
