We managed the media scrum when Prince William was a student at the University of St Andrews. In his four years of studies, the heir to the throne did not put a foot wrong or speak one word out of turn.

Despite the burning glare of attention from the world’s tabloids, he and his girlfriend Kate remained as cool as cucumbers and presented inscrutable smiles to the world.  

It distresses me, therefore, that his brother Harry is behaving like a teenage pop star, singing his heart out in a series of newspaper revelations that detract from the mystery of the monarchy.

Harry – I sympathised when you lost your mum. I accepted your bad boy behaviour as a teen but I don’t buy the reluctant royal revelation. You enjoy your royal status far too much to quit The Firm.

Harry – now that you’ve put up, it’s time to shut up…for good!
