Give her a chance, it takes a decade to fully qualify as a doctor so she's only at the halfway point
She'll have two years compulsory foundation training next and then more depending on what she's going to specialise in but at least she should get paid from now on. Both her parents are doctors so Pete would be in very hot water if he expected her to give it up to become a celebrity consort but there's no suggestion that he does. He's said that her career is more important and he likes the fact they will have such different jobs. She probably enjoys the chance to dress up and accompany him to events and it doesn't appear to have distracted her from her studies so far.
Loved the photo of her looking at Juniors tonsils in his column this week, in case any of us forgot she was training as a doctor.
