The decision to tell trans girls (biological males identifying as female) they must leave Girlguiding by September is the right one

Girlguiding, the UK's largest girl-only youth organisation, has decided that transgender girls must leave by September 6, 2026. The decision has prompted strong reactions from both supporters, and critics.

It follows a 2025 UK Supreme Court ruling defining "sex" as biological sex under the Equality Act 2010.
