The Communist Forum was a short-lived political group formed in 1986 by Mike Banda, following expulsion from the Workers Revolutionary Party (Workers Press) - itself one half of the 1985 split in the WRP. The group moved away from orthodox Trotskyism. It was renamed the Marxist Philosophy Forum in 1987 and died out shortly afterwards.
Mike Banda died in 2014.
