The debate over single-sex spaces in the UK, particularly in the NHS, has escalated due to a tribunal case involving nurse Sandie Peggie, who objected to sharing a changing room with a transgender woman. Scottish Labour leader Anas Sarwar has urged the Scottish government to provide clearer guidance on access to these spaces, emphasizing the protection of single-sex spaces based on biological sex. The Scottish government maintains that current laws, including the Equality Act 2010, are clear, but public bodies face challenges in implementing policies, leading to calls for more explicit instructions. The ongoing tribunal and a Supreme Court case highlight the legal complexities and lack of consensus on defining single-sex spaces, leaving organizations to navigate the issue on a case-by-case basis.
