Green-run councils in London, including Lambeth and Waltham Forest, say they intend to resist new guidance on single-sex spaces. The councils’ position centers on concerns that the proposed guidance could lead to discrimination against trans people. The Evening Standard reports that Lambeth and Waltham Forest have already signaled their opposition, framing the guidance as a potential risk to how trans people are treated in settings covered by single-sex rules. Yahoo UK News carries the same headline but provides no additional details in the provided excerpt. Across the reporting, the dispute is focused on how single-sex spaces are defined and how trans-related policies would apply in practice under the forthcoming guidance. The sources agree on the basic facts: that these councils are Green-led, that Lambeth and Waltham Forest are named specifically, and that they plan to resist the guidance due to stated concerns about discrimination. No further information is provided here on the content of the guidance, the decision-making process, or any alternative proposals from the councils.
