yes. Until Labour confirm that when they are discussing 'biological sex' that they do not include those male people who have now got that certificate that treats them for all purposes as female, then this will remain ambiguous.
This is what has been said by Keir Starmer:
A woman is a female adult, and in addition to that trans women are women, and that is not just my view — that is actually the law. It has been the law through the combined effects of the 2004 [Gender Recognition] Act and the 2010 [Equality] Act. So that’s my view. It also happens to be the law in the United Kingdom.

Therefore, this is ambiguous that Starmer now means whether the term 'women' now means only female people when referring to single sex.Strangely, clearing this up would be very simple and would be a vote winner obviously. As pointed out why Sunak has done this. Why are Labour not making this very clear as Kemi has?
