Prince Harry has shared that his brother has been 'plotting revenge' on him since they fought as young boys, with an incident in Scotland showing the Duke his sibling's true colours.
In Harry's new memoir, Spare, he goes into detail about almost every aspect of his family life, from a young boy to a man with a wife and two children. He also describes the struggles he has suffered at the hands of his family - in particular his brother William and father, King Charles III.
Early on in the book, Harry describes how he and his sibling would fight often if there were "no other common enemies around", and during one scuffle in Scotland, it all came to a head.
