On 16th April 2025 the Supreme Court of the United Kingdom clarified that sex in the Equality Act 2010 meant biology. The National Federation of Women's Institute continues to allow men who think they are women to join and excludes men without the protected characteristic of "gender reassignment". It is highly likely that this is illegal discrimination.

Not only is it legal, it is necessary to exclude this subset of men, to ensure the Women's Institute is acting inside its constitution, which states "membership is open to women" and to comply with charity law.

We want the WI to follow the law and exclude men from its membership, no matter how they identify.
