In page Vyacheslav Molotov:

"

Molotov was criticised by Lenin and Leon Trotsky, with Lenin noting his "shameful bureaucratism" and "stupid behaviour".[1] On the advice of Molotov and Nikolai Bukharin, the Central Committee decided to reduce Lenin's work hours.[10] In 1922, Stalin became General Secretary of the Bolshevik Party with Molotov as the de facto Second Secretary.[citation needed] As a young follower, Molotov admired Stalin but did not refrain from criticising him.[11] Under Stalin's patronage, Molotov became a full member of the Politburo in January 1926.[6]
