The author added that Charles had a habit of changing clothes, up to four times a day.
The then Prince of Wales allegedly had a strict ritual as to how he liked to spend his day.
King Charles was sensationally attacked in Omid Scobie’s Endgame which claimed the monarch’s “habits and way of life suggest a disconnect”.
Scobie added that even his mother, the late Queen Elizabeth “repeatedly complained about Charles’ extravagantly luxurious lifestyle”.
The author even alleged that Charles had “night tantrums” too.
Scobie wrote: “There have been reports of temper tantrums at night as well: if the prince’s pyjamas aren’t pressed, sources have claimed, there is hell to pay.”
