I am not quite sure how this came about, but there is a survey being circulated about setting up a Women's Centre in Leeds by Women and Girls Alliance in Leeds https://womenandgirlsallianceleeds.org.uk/
There are a lot of questions about "Women Only" provision, but doesn't specify what they mean by women only.
And at the end they ask about gender, prior to asking about sex (well at least they ask about sex). But no option to say you dont have a gender other than in the space for other gender identity where I suppose you could say none.
I am not in Leeds, and doubt they want to hear from anyone from other areas, but though anyone in or near Leeds who hasn't seen this might be interested.
Even if only to get this Alliance to be more specific about Women Only, whilst reminding them that single sex provision is legal!

(If I remember rightly Leeds Council has been quite anti sex based rights, so wonder if this shows a slight shift in position?)
