Callinicos first became involved in revolutionary politics as a student at _Balliol College, Oxford, and his first writings for the International Socialists (forerunners of the SWP) was an analysis of the student movement of the period. His later writings soon established him in socialist and academic circles as an expert on southern Africa and the French philosopher Louis Althusser. A talented writer and speaker, by the early 1980s he was elected to the Central Committee of the SWP, a position he retains today. In recent years he has been responsible for the SWP's international work, but he has seen a number of splits in the International Socialist Tendency's affiliated groups.

He participated in the Counter-Summit to the IMF/World Bank Meeting in Prague, September 2000 and the demonstration against the G8 in Genoa, June 2001. He has also been involved in organising the Social Forum movement in Europe. He is a contributor to J. Bidet and E. Kouvelakis, eds., Dictionnaire Marx Contemporain (Paris: Presses Universitaires de France, 2001), and has written a number of articles in New Left Review. In Redemption, Tariq Ali's Trotskyist satire, he is depicted as the redundant intellectual "Alex Mango".
