SIR Keir Starmer must apologise to women who were cancelled because of trans extremism, Kemi Badenoch demanded last night.

The Tory Leader blasted the PM for spending years dithering over how to define a woman and only making a decision following the landmark Supreme Court ruling.

Ms Badenoch said: “The Prime Minister should apologise to the many women who have been harassed and hounded out of their jobs by groups who have misapplied the Equality Act.

“If Keir Starmer’s government really do respect the judgment, they should take a stand against the extremists who still believe it is acceptable to intimidate women.”

She will press the PM on the issue face-to-face at a showdown PMQs this afternoon.

It comes after Sir Keir finally broke his silence on the judgement yesterday, declaring he welcomes the “clarity” it brings and stating that a woman is an “adult female”.

The PM previously argued “trans women are women” and even said that one in every thousand women can have a penis.

But back from his Easter holidays yesterday, Sir Keir said that “a woman is an adult female, and the court has made that absolutely clear”.

However, Harry Potter author JK Rowling has now hit out against the PM despite his latest comments.

Posting on X, formerly Twitter, she said: “Imagine being such a coward you can only muster the courage to tell the truth once the Supreme Court has ruled on what the truth is.”

Rowling has been a long standing advocate for women’s group For Women Scotland, which she is also believed to have backed with funding.

The author has bravely stood firm in the face of online pressure for years.

In another tweet last night, Rowling said: “Women have fought (and are still fighting) the single biggest land grab on their rights in my lifetime.

“Some have sacrificed their livelihoods and safety to combat a pernicious ideology that has infiltrated elite institutions, including government.”

She also posted a picture on X of Sir Keir and other Labour MPs – including Foreign Secretary David Lammy and Angela Rayner – with previous quotes they have made in support of trans women. 

Rowling accused them of siding “with the persecutors” and questioned whether any of them would “issue an apology or admit that they made a serious error in siding with well-funded activist groups lying about what the law actually said”.

The author said that actions of the past have “had measurable, severe impact on some of society’s most vulnerable women”.

In 2020, the esteemed author slammed the growing trend of replacing “biological sex” with “gender identity”.

It was Rowling’s beloved group For Women Scotland which also launched a long-running legal battle with the Scottish government over how a “woman” was defined in Scottish law.

In the UK, a growing number of women have reported facing harassment, professional consequences, or social exclusion for expressing views on sex and gender that conflicted with prevailing trans-inclusive policies.

In 2019, Maya Forstater lost her job at a think tank after tweeting that biological sex is immutable, sparking a landmark tribunal case on free speech and gender beliefs.

In 2021, Rosie Duffield, a Labour MP, faced intense backlash and threats for stating that only women have cervixes, leading her to skip her party’s annual conference over safety concerns.

That same year, Kathleen Stock, a philosophy professor at the University of Sussex, resigned after facing student protests and threats over her gender-critical views.

And in 2022, NHS nurse Amy Gallagher launched legal action claiming she was subjected to harassment during diversity training for expressing that gender ideology conflicts with her Christian beliefs.
