JK Rowling has taken to social media to issue a statement following the Supreme Court's ruling over what defines a "woman" in law.

Concerns from campaigners have been rife for years that women's rights had been watered down to appease trans activists.

And on Wednesday, Britain's top judges unanimously agreed the terms "woman" and "sex" in gender legislation will solely refer to a biological woman and biological sex.

The ruling has been celebrated by numerous biological women's rights advocates, particularly For Women Scotland who spearheaded the calls for the courts to make the ruling.

It took three extraordinary, tenacious Scottish women with an army behind them to get this case heard by the Supreme Court and, in winning, they’ve protected the rights of women and girls across the UK. @ForWomenScot, I’m so proud to know you ???????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? https://t.co/JEvcScVVGS

The likes of Sharron Davies, Duncan Bannatyne, Graham Linehan and many other famous faces have also spoken out to laud the ruling.

Now, Rowling has followed suit after years of being a vocal supporter of biological women's rights and same-sex spaces.
