The Minorities Research Group (MRG) was the first organisation to openly advocate the interests of lesbians in the United Kingdom. It was founded by four women who got together in response to an article that was published in the magazine Twentieth Century. The group published the Minorities Research Group Newsletter, and went on to publish its own lesbian magazine called Arena Three that provided a lifeline to remote lesbians around the country.

Esme Ross-Langley, was a British writer, best known as the founder of the Minorities Research Group and Arena Three.
