Series 1, Episode 1: It’s the book that should be on every royal fan’s bookcase, ‘Diana: Her True Story – In Her Own Words’. As the only book Princess Diana ever cooperated with, Kate Thornton dissects the process to publication with the author Andrew Morton and relives some of the revelations with Richard Kay, now the Daily Mail’s Editor at Large, and Royal Biographer Ingrid Seward who were at the centre of the media frenzy in 1992 when the book hit the stores.
