Internationalist Communist Organisation

The Internationalist Communist Organisation (French: Organisation Communiste Internationaliste, OCI) was a Trotskyist political party in France. Its successor is the Internationalist Communist Current of the Workers Party.

The group's origins lay in the Internationalist Communist Party (PCI), the French section of the Fourth International. In 1952, the Fourth International removed the Central Committee of the PCI, and replaced it with one built around Michele Mestre and Pierre Frank, who were more favourable to the International's policies. This led the majority of the PCI to form a new organisation, also known as the Internationalist Communist Party, and led by Pierre Lambert and Marcel Bleibtreu.

In 1953, the Fourth International suffered a major split, and the Socialist Workers Party of the United States, the British group The Club and some smaller groups forming the International Committee of the Fourth International, with Lambert's PCI.

The PCI supported the FLN during the Algerian War of Independence. Disagreements over which faction to support led Lambert to expel Bleibtreu from the PCI in 1955.

Future Prime Minister of France, Lionel Jospin, joined the group in 1960 and remained an active member for over ten years.
