A serialization of Penny Junor's new anti-Diana and pro-Charles biography of Prince William in The Daily Mail today provides the astonishing revelation that William was deeply upset by his mother's interview on Panorama, in which she uttered the famous words, "There were three of us in this marriage, so it was a bit crowded."One of his friends says: "Imagine what it must have been like to live through the s**t of William’s childhood: the divorce, the acrimony, the shame of it all being played out in public, his mother’s Panorama interview, then she’s dead. His father’s mistress hanging around, then moving in."It makes you shudder. Even if you were living on a sink estate, you’d feel sorry for your neighbour if they’d gone through that."
