LGB Alliance

The LGB Alliance is a British advocacy group and registered charity founded in 2019 in opposition to the policies of LGBT rights charity Stonewall on transgender issues. Its founders are Bev Jackson, Kate Harris, Allison Bailey, Malcolm Clark and Ann Sinnott. The LGB Alliance argues that the sex-based rights of those who are same-sex attracted are threatened by the inclusion of trans people. The group has opposed a ban on conversion therapy that includes trans people in the UK, opposed the use of puberty blockers for children, and opposed gender recognition reform. The group intervened at the UK Supreme Court in the case of For Women Scotland Ltd v The Scottish Ministers, which clarified the meanings of sex and sexual orientation in the Equality Act 2010.

The LGB Alliance has been described as transphobic, "anti-trans", "trans-exclusionary", a "hate group" and as part of an "anti-transgender movement" by scholars, politicians, LGBT organisations, human rights organisations, and others, including the Labour Campaign for Trans Rights and several Labour MPs. The group has said that it is "not anti-trans". It has received support from UK politicians including former prime minister Boris Johnson (Conservative), Rosie Duffield (Independent), Sarah Ludford (Liberal Democrat) and Joanna Cherry (SNP).

The LGB Alliance was granted charitable status by the Charity Commission for England and Wales in April 2021, which was controversial with LGBT groups in the UK, fifty of whom signed an open letter condemning it. A hearing for an appeal against its charitable status started in the First-tier Tribunal in September 2022. The appeal was dismissed in July 2023. It found that Mermaids, which had made the appeal, did not have legal standing to challenge the decision by the Charity Commission. The judges also said they had been unable to reach agreement on whether LGB Alliance qualified for charitable status and therefore had not ruled on that matter.
