Was that really Peter Mandelson getting into a police car on Monday? Was it really the same Mandelson who had supposedly been about to flee to the British Virgin Islands, the man called “a traitor” to his country and the buddy of a sex trafficker of girls? Was he really to be questioned for nine hours by the police over “misconduct in public office”, an offence few people have ever heard of?
