On June 29th 1985, London’s Gay Pride March was led by
members of the Dulais community, other miners, and official
representatives of the mine worker’s union, in a show of
thanks and solidarity for LGSM’s (Lesbians and Gays Support the Miners) overwhelming support during
the miner’s strike.

In September 1985, at the Labour Party Conference, a motion
was tabled to enshrine Gay and Lesbian rights into the
party’s official manifesto. Although the motion had been
raised many times before, this time it was carried without
objection. This was due, in no small part, to a block vote of total approval from the largest Union at the
conference: the National Union of Mineworkers.
