Nikolai Yezhov
Nikita Khrushchev, along with Vyacheslav Molotov and Nikolai Yezhov, were sent to take over Postyshev's post in Ukraine. Khrushchev had to be appointed by Moscow; he could not be elected because, after Postyshev's removal, the entire Central Committee of the CP(b)U "had been purged spotless," according to Khrushchev.
