King Charles III had no idea what cling film was and “shrieked” the first time he saw it, an author has claimed in an unauthorised biography which detailed a selection of interesting stories about our new monarch.

Author Tom Bower said he interviewed over 120 people for his biography of Charles, entitled ‘Rebel Prince’.

The book delves into Charles’s struggles to overcome unpopularity, and includes some pretty unexpected tales along the way.

Explaining how the royal reportedly had his first encounter with cling film, Bower wrote: “He walked into the dining room and shrieked. Fearing the worst, Camilla dashed in after him. ‘What’s this?’ asked her husband, pointing at the food.

“’It’s cling film, darling,’ she replied.”
