Professor Alan Crockard, one of the main figures behind the Modernising Medical Careers (MMC) fiasco that has recently been Destroying Doctors' Careers today handed in his resignation. This information has been circulated to members of the board of PMETB - the Postgraduate Medical Education and Training Board, who will undoubtedly reveal more information tomorrow. The resignation calls into doubt the continued implementation of the current training reforms for junior doctors, leaving uncertainty hanging over thousands.
