"In 1926, Joseph Stalin's manoeuvres inside the Bolshevik party moved Gramsci to write a letter to the Comintern in which he deplored the opposition led by Leon Trotsky but also underlined some presumed faults of the leader. Togliatti, in Moscow as a representative of the party, received the letter, opened it, read it, and decided not to deliver it. This caused a difficult conflict between Gramsci and Togliatti which they never completely resolved"
