The Revolutionary Communist League was a small Trotskyist group in Britain. It was founded in 1970 by two small groups, one expelled from the International Marxist Group for wanting it to focus on entryist work in the Labour Party, and one from Militant.
The League promoted the Socialist Charter initiative of Tribunite Labour MPs which published the Chartist paper, and were consequently nicknamed the Chartists. They took over this initiative, and based their work around the Charter on a conception of transitional politics taken from Leon Trotsky. They were also active around The Soldiers' Charter, an attempt to influence the armed forces.
By 1973 most of the group were moving to the right, while others (including Al Richardson) had left. A split developed and the Right of the group kept the journal, which developed a politics influenced by Euro-Communism and were close to the Labour Co-ordinating Committee. The Chartist Minority around figures such as Graham Bash and Keith Veness became involved in the launch of London Labour Briefing.
