The group was formed at a meeting on May 10, 1990, called after the murder of gay actor Michael Boothe (which occurred on the previous April 30). Many of those involved in calling this meeting had been members of the Organisation for Lesbian and Gay Action (OLGA) which had itself arisen out of the campaign against Section 28. There were four principal founders: Simon Watney, Keith Alcorn, Chris Woods and Peter Tatchell. Between 40 and 60 people attended the first meeting, including many who had been active in the Gay Liberation Front and other campaigns.
