After the October Revolution, differences emerged inside the party. In 1921, the party issued the "Platform of the Russian Social Democratic Labour Party", calling for liquidating the political monopoly of the Communist Party, which was identified as something quite different from the dictatorship of the proletariat, privatizations of large sectors of industry and giving full voting rights to the peasantry and those treated by the Soviet government as the bourgeois class. From the beginning of 1921 after the suppression of the Kronstadt garrison revolt, the 10th Communist Party Congress and the introduction of the New Economic Policy (NEP) and ending of forcible confiscation of grain from the peasantry, the Russian Social Democratic Labour Party was forced to operate underground in Soviet Russia and the Soviet Union and openly only in exile in Europe and North America. The Foreign Delegation of the party had been established in 1920 and was at first located in Berlin (until 1933), then shifted to Paris and in 1940 moved to New York City. In exile, the party consisted of small groups in Geneva, Liège, Berlin, Paris, Bern and New York City. Martov and Abramovich chaired the Foreign Delegation until 1923, when it was chaired by Fyodor Dan and Abramovich. Aron Jugov was the secretary of the Foreign Delegation.
