Prince Harry may face what is colloquially and appropriately known in English slang as 'a bollocking' from his army bosses for damaging the reputation of the army.

The guidelines state that members of the army must not display any “social misbehaviour”, especially if it results in any damage to corporate image or reputation.

A former instructor at the Royal Military Academy Sandhurst, told the Telegraph that the Prince is most likely to face an “interview without coffee”.

“It is very stupid doing that anywhere near cameras,” he said. “I don’t know how his minders let that happen. My view is that he will probably get a telling off. If he’d just come back from active service and was letting off steam it might be different.”
