The International Committee of the Fourth International (ICFI) is the name of two Trotskyist internationals; one with sections named which publishes the World Socialist Web Site, and another linked to the Workers Revolutionary Party in Britain.
The International Committee originated as a public faction of the Fourth International. It was formed in 1953 by a number of national sections of the FI that disagreed with the course of the International Secretariat of the Fourth International led at that time by Michel Pablo (Raptis) and Ernest Mandel (Germain). The Committee was co-ordinated by the American section, the Socialist Workers Party, and included the British section led by Gerry Healy and Pierre Lambert's Parti communiste internationaliste (PCI) in France. Trotskyist groups in various other countries, notably in Austria, China, India, Japan, New Zealand and Nahuel Moreno's group in Argentina, also joined.
The grouping's founding statement was an open letter of the National Committee of the SWP which outlined the disputes it had with Pablo's faction within the International Secretariat of the Fourth International. It reiterated what it saw as the basic principles of Trotskyism and described the direction of the "Pabloite" faction as "revisionist", claiming that this threatened the survival of the Fourth International, the liquidation of the Trotskyist program and definite steps taken towards its organisational liquidation. As an example, the letter explained that Pablo expelled a majority of the French section of the International, because they disagreed with the International's policy of working within the Stalinist Communist Party of France. This policy was described as one of entrism sui generis, entryism of a special kind, in which the Trotskyists were to join the Stalinist or Socialist mass parties with a long term perspective of working within them.
