Official rules requiring women-only spaces to be organised according to biological sex have come into force across England, Scotland and Wales, giving campaigners long-awaited clarity after years of institutional confusion. A biological male may therefore be excluded from a women-only area where doing so is considered a proportionate way to protect safety, privacy or dignity. Challenges are expected from transgender activists as well as women’s rights groups seeking to enforce the Supreme Court judgment. However, several London councils run by the far-left Green Party are preparing to resist the guidance.
