"It is necessary to explain that when one speaks of the P.S.U.C. ‘line’ one really means the Communist Party ‘line’. The P.S.U.C. (Partit Socialista Unificat de Catalunya) was the Socialist Party of Catalonia; it had been formed at the beginning of the war by the fusion of various Marxist parties, including the Catalan Communist Party, but it was now entirely under Communist control and was affiliated to the Third International. Elsewhere in Spain no formal unification between Socialists and Communists had taken place, but the Communist viewpoint and the Right-wing Socialist viewpoint could everywhere be regarded as identical."
