Revolutionary Communist League of Britain (RCLB)

The Revolutionary Communist League of Britian (RCLB) was formed in 1977, after merging with other small Marxist-Leninist groups. 

The RCLB published the paper Class Struggle from 1973 until around 1990, the journal Revolution from 1976 to 1980 and the journal October up until the group dissolved in 1998. 

There are a handful of Special Branch reports on the organisation, although there is not much evidence it was targeted by any particular SDS officer,  unit boss HN135 Mike Ferguson indicated to MI5 that the SDS had a source in the group in Feburary 1979.
