Lavrenty Beria
There was a coup d'état led by Nikita Khrushchev with the military forces of Marshal Georgy Zhukov. Beria was arrested on charges of treason during a meeting in which the full Politburo condemned him. This was all planned by Krushchov. The NKVD was powerless because Zhukov's troops were there. After interrogation, Beria was taken to the basement of the Lubyanka and shot, as were six of his associates.
