A devout Christian French teacher who was pictured in bed with a 17-year-old pupil has been found unfit to work with children, despite her husband denying the tryst took place.

Isabelle Graham, 28, was accused of repeatedly “engaging in sexual activity” with a pupil after being photographed with him in a Travelodge in Edinburgh after a prom night. She denied the charge. A disciplinary hearing found yesterday that she was guilty of charges against her and has been barred from the profession by the General Teaching Council for Scotland (GTCS).

The investigation began after a picture appeared on social media following the prom night in June 2014.
