JK Rowling has said she won’t forgive Harry Potter stars Daniel Radcliffe and Emma Watson after slamming celebrities who ‘cosied up to a movement intent on eroding women’s hard-won rights’.

The multi-millionaire author hit out at stars who use their ‘platforms to cheer on the transitioning of minors’ after the release of the long-awaited Cass report into gender treatment in the UK.

The vocal women’s rights campaigner said people who supported gender transitioning in children should apologise to ‘traumatised detransitioners and vulnerable women reliant on single sex spaces’.
