Answer
After Nikita Khrushchev was ousted in 1964, Suslov supported the collective leadership of Leonid Brezhnev, Alexei Kosygin, and Nikolai Podgorny. This type of leadership was seen as a way to avoid the cult of personality that had developed around Khrushchev and to prevent one individual from becoming too powerful. The collective leadership system worked well for several years, but eventually it broke down and Brezhnev emerged as the dominant leader.
