Now JK Rowling labels Sturgeon one of the 'mean girls'! Harry Potter author likes tweet comparing SNP leader to high school bully Regina George for implying she is not a 'real feminist' unlike her in deepening trans rights row

A mockup of the poster for Mean Girls (2004) showing JK Rowling and Nicola Sturgeon's faces superimposed over the characters' faces is being widely shared on social media. The Harry Potter author and the First Minister are at loggerheads over trans-issues and the Scottish Government's legislation to make it quicker and easier for individuals as young as 16 to change sex with no requirement for medical reports or evidence. Yesterday Ms Rowling branded the SNP leader a 'destroyer of women's rights' - wearing a T-shirt with it as a motif - and today Ms Sturgeon ratcheted up the row by suggesting that the author is not a 'real feminist' - and that she is. Ms Rowling, who is opposed to Scottish independence and donated £1million to the campaign to stop it, has yet to respond publicly to the latest barb but she has liked a tweet this afternoon from a supporter who was upset by the First Minister's comments. The message said: 'Her [Sturgeon's] intonation on "real feminist" was, for me, an ugly reminder of the school playground when the mean girls would circle me and taunt me for being too poor, or too clever, or simply weird. At heart, Sturgeon is one of the mean girls'. The term 'mean girls' was popularised by the 2004 movie of the same name. Its protagonist Regina George, played by Rachel McAdams, has been branded the world's most evil high school student .
