Cliff also backed Haston when he disputed the growing sympathies of the FI for Josip Broz Tito's Yugoslavia, but by this time Haston was growing demoralised and would soon drop out of revolutionary politics entirely. Cliff however was beginning to develop the idea that the Union of Soviet Socialist Republics was a bureaucratic state capitalist society, prompted in part by earlier arguments pointing in this direction from Haston. Much later Cliff in his autobiography would acknowledge the debt he felt to Haston. There is an irony in this as it has been suggested that Cliff had been briefed by the leadership of the FI, while passing through France, to oppose Haston on just this question, although no proof of this has been made public.
