Interview with Harriet Harman. To me she seems to be arguing blanket bans aren't legal i.e. case by case basis.

The current debate about trans rights was foreseen, she claims, when as women and equalities minister she co-authored the landmark Equalities Act back in 2010, alongside then-solicitor general, Vera Baird.
“All those discussions about discrimination against trans women and men and the interaction with single-sex services were all envisaged,” she said.
Equalities is about achieving a balance, she says, and this can be hugely challenging. “For example because of the idea of protection of freedom of religion, religions are allowed to discriminate on grounds of sex. You’re not forced to have a woman in all religions, with equal access [as] men.”
She regrets that the row around women and trans rights has taken a “toxic” turn. A current flash point is concern over discrimination against trans women on the grounds of sex in specific settings such as a domestic violence refuges or rape crisis centres.
Harman says the Equality Act ensures there is no blanket ban on trans women accessing services, but there are circumstances in which single sex-services may exclude some individuals, and she thinks this is right.
“The fundamentals of the Gender Recognition Act (2004), and the Equality Act (2010), remain sound – that you should protect trans people from discrimination, and transphobia, but you should also have exceptions, which are able to be used but on a narrow basis, not on a blanket basis.”
Harman says Scotland, which is moving faster than England over what the exact process for gender recognition should be, will provide helpful context to some of the debate, and she also anticipates court cases over access to single-sex services.
