Cressida Dick 2 year extension

So Cressida Dick is to be offered another two years as head of Scotland Yard. But several high flying figures, all victims of police corruption, incompetence and malpractice, have penned an open letter to Boris Johnson strongly opposing another two year contact for her. I'm inclined to agree. Nothing I've heard about this woman inspires confidence and I don't really understand how she got the job in the first place. She should go and about time too.
