David Cannadine traces 75 years of the BBC's relationship with the Royal Family, from the awed reverence of the early Richard Dimbleby broadcasts, through royal marriages, divorces, deaths and It's a Royal Knockout. He discovers how the Palace reacted to the dramatic revelations made by Diana, Princess of Wales, in her Panorama interview, and hears what the BBC's royal correspondent Nicholas Witchell thought of being branded 'that awful man' by Prince Charles. With contributions from former Palace press officers, the film-maker and author of On Royalty Edward Mirzoeff, Jeremy Paxman and the BBC's official historian Professor Jean Seaton.
