Comintern interventions could trigger right-wing internal opposition in national parties.

Evidence

Gramsci— who argued that the P.S.I. with whom the Comintern wished the communists to fuse was fundamentally a peasant rather than a proletarian party! Kolarov’s intervention was of critical importance for future developments in the party, since it stimulated the emergence of a right-wing opposition group headed by Tasca, who stood for a full application of the united front policy. However, for the moment the Bordigan executive was reconfirmed by the congress as a united bloc; the right minority was not represented in the party’s leading bodies; and Gramsci was sent to Moscow as the P.C.I. representative to the Comintern Executive. — Antonio Gramsci, Selections from the Prison Notebooks, 123
