Pierre Lambert

Lambert began his activity as a Trotskyist militant before the Second World War when he was a member of the Internationalist Workers Party (POI) led by Raymond Molinier.

After the war he continued his activism, as a member of the now united French section of the Fourth International, the Internationalist Communist Party (PCI).

By this time, 1952, the PCI had split into two mutually hostile groups on the question of entrism sui generis and the associated perspective of hundreds of years of deformed workers states propagated by Pablo.

As leader of the PCI by 1954 Lambert forged an alliance with the Socialist Workers Party in the United States and others opposed to Pablo.

This was supported by the US SWP but the Nicaraguan Revolution intervened in 1979 and instead the OCRFI eventually united with Nahuel Moreno's group to form the Parity Committee for the Reconstruction of the Fourth International.
