From Wikipedia, the free encyclopedia.
The International Marxist Group (IMG) was a Trotskyist political party in the United Kingdom. They published the newspaper Red Weekly.
It emerged from a group of International Secretariat of the Fourth International (ISFI) loyalists, including Ken Coates within the Revolutionary Socialist League (RSL), who launched a magazine, The Week. They then split from the RSL to form the International Group. After the ISFI became the United Secretariat of the Fourth International, they ordered the RSL to united with the International Group. This happened in 1964, but very soon the former International Group members split to form a new International Group, the remaining RSL leaving the international and becoming the Militant Tendency.
In 1968, the group renamed itself as the International Marxist Group, and became prominent when Tariq Ali led protests against the Vietnam War. The IMG began to focus on work in the student movement, expelling some members who formed the Revolutionary Communist League. During the 1970s, increasing division appeared in the group, but it remained fairly large and launched the Socialist Unity initiative for the 1979 general election.
In 1981, the IMG renamed itself as the Socialist League. The group entered the Labour Party and began publishing the Socialist Outlook newspaper. When this group disintegrated, a minority split to form Socialist Action, while a majority formed a third International Group, which in 1987 merged with the Socialist Group to form the International Socialist Group.
