During royal trips, he allegedly loads up his must-have possessions, including his own bed linen, rolls of Kleenex Premium Comfort lavatory paper, Laphroaig whisky, bottled water and two landscape paintings of the Scottish Highlands.
The book, Rebel Prince: The Power, Passion and Defiance of Princess Charles by investigative journalist Tom Bower, is being serialised in the Daily Mail and claims the 69-year-old heir to the throne makes five outfit changes a day.
The author also lifts the lid on the Prince’s domestic life and says his wife Camilla heard Charles shriek in the kitchen when he went to see what was for dinner.
When, fearing the worst, she dashed in, her husband asked: “What’s this?”
She is said to have replied: “It’s clingfilm, darling.”
The book also says that a weekend with the Prince at his Sandringham home can be a “decidedly odd experience”.
A group of journalists and writers who were invited five years ago were each assigned a servant.
After dinner on Fridays was listed as cinema night and the chosen film was Robert Altman’s Gosford Park which depicts an upper class lifestyle not dissimilar to the Prince’s.
