Girlguiding Requires Trans Girls to Leave by September 2026

Girlguiding, the United Kingdom's largest girl-only youth organization, has instructed its current transgender girl members to leave by September 6, 2026, following a Supreme Court ruling on the definition of sex under equality laws. The policy update, shared with members on Tuesday, builds on a December announcement that barred new transgender girls from joining starting December 2, 2025.

The organization, which serves around 300,000 girls aged four to 18 through its Rainbows, Brownies, Guides, and Rangers programs, along with 80,000 volunteers, stated that the changes ensure compliance with its governing documents and legal obligations. In a statement, Girlguiding explained, "This allows affected members and their families time to plan, prepare, access support, and decide when between now and September they feel ready to leave." Transgender girls and young women currently volunteering in women-only roles must transition to positions open to all volunteers by the same deadline.

The decision stems from the Supreme Court's April 2025 unanimous ruling that the terms "woman" and "sex" in the Equality Act 2010 refer to biological woman and biological sex. Girlguiding officials said...
