JK Rowling has hit back at Nicola Sturgeon after the former Scottish first minister's memoir reignited their long-running row over gender.

In the book, Sturgeon said she had endured a surge of "vile" abuse after Rowling posted a selfie in a T-shirt with the slogan: "Nicola Sturgeon, destroyer of women's rights".

Sturgeon said it had made her feel "more at risk of possible physical harm".

Defending her actions, Rowling accused Sturgeon of a shameless denial of reality over transgender issues.

In a review of the book, published on her own website, Rowling said her intention had been to encourage journalists to "confront" Sturgeon on the topic.
