GB News descended into a bitter trans row live on-air as presenter Ben Leo clashed with a panellist over the recent UK Supreme Court ruling that defined a ‘woman’. The bombshell ruling decided that ‘woman’ is based on biological sex, protecting cisgender women in single-sex spaces. But panellist Jonathan Lis slammed the ruling as “nonsense”.

He fumed: “The native toilet is a women’s loo if you’re a trans man, and the Supreme Court judgment is saying those men can be lawfully excluded from a female-only space if it’s reasonably considered that their male attributes make them men. So basically, what the Supreme Court is saying is that your biology determines who you are, except if your appearance happens to trumpet the law. That judgment is complete nonsense, and it’s incoherent.”

Commentator Lee Harris disagreed, blasting: “We have been living in proper confusion for years, and now we have clarity.

“We had no clarity because it was being fudged, so the word woman was being not necessarily linked directly to biological sex, which led to the confusion. Now we have clarity and it’s very simple, there’s a very simple answer – if you are a trans woman, you will use the men’s toilets. You will use the biological sex and there is no confusion.”

Presenter Ben fumed that he is “sick of the debate”, fuming: “Do what you want – we’re a liberal country, I don’t care what you do, just stay out of women’s toilets.

“I don’t want to talk about trans anymore, it does my head in quite frankly. Because as I said, we get bogged down in all this stupid debate, when women can’t be men and men can’t be women, and the Supreme Court ruled that.”

Lis explained that the science is “not as clear cut” as it might seem, as cisgender men are sometimes born with XX chromosomes, and cisgender women with XY depending on genes – which can muddy the waters.
