So I think I've got myself confused - I'm googling what the current rules are about self-identification I came across this article, published in July 2017
www.bbc.co.uk/news/uk-40713645
"At present, the guidance issued to service providers - women's refuges, for example - by the Equality and Human Rights Commission states: "Where a transsexual person is visually and for all practical purposes indistinguishable from someone of their preferred gender, they should normally be treated according to their acquired gender unless there are strong reasons not to do so."
Those with a GRC "should be treated in their acquired gender for all purposes".
That means that anyone who identifies themselves as a woman - whether that is their legal status or not - can already use separate-sex facilities such as changing rooms, toilets or single-sex gyms.
The proposed changes to the gender recognition act does not change that."
So transwomen can already use all-women facilities eg women only swimming sessions etc? What will the changes actually do in practice?
It also says there are separate rules in sports and the sporting bodies make their own rules for gender identification - so I guess any change in law wouldn't affect that?
