Trainees are being abused by senior male surgeons, a major analysis given to the BBC reveals.

Sexual harassment, sexual assault and rape have been referred to as surgery’s open secret.

There is an untold story of women being fondled inside their scrubs, of male surgeons wiping their brow on their breasts and men rubbing erections against female staff. Some have been offered career opportunities for sex.

The analysis - by the University of Exeter, the University of Surrey and the Working Party on Sexual Misconduct in Surgery - has been shared exclusively with BBC News.

Nearly two-thirds of women surgeons that responded to the researchers said they had been the target of sexual harassment and a third had been sexually assaulted by colleagues in the past five years.

Women say they fear reporting incidents will damage their careers and they lack confidence the NHS will take action.
