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.”
