The BBC has issued presenter Dame Jenni Murray with an impartiality warning over her transgender comments as a TV presenter called for her to be sacked.

Dame Jenni, the veteran host of Woman’s Hour, has been told that she must remain impartial on “controversial topics” after she claimed that a sex change can’t make a man a "real woman".

The claims, which have been fiercely criticised by equality campaigners, have resulted in Dame Jenni being reminded that she must remain neutral on the subject.

It comes as the subject of Dame Jenni’s comments, transgender presenter India Willoughby, labelled her a “dinosaur” that had misused her position for “spouting bile”.
