LGB Alliance

The LGB Alliance is a British anti-transgender advocacy group. It was 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 rights of transgender people conflict with those of cisgender lesbians, bisexuals, and gay men and that same-sex attraction is endangered 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 ruled that the terms woman and sex in the Equality Act 2010 refer exclusively to biological sex.

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 LGB Alliance was granted charitable status in April 2021, after the organisation agreed to revise its social media policies. A legal challenge against this decision was dismissed in 2023 on the grounds the plaintiff lacked legal standing, without a ruling on whether LGB Alliance qualified for charitable status.
