Queen Elizabeth was once spotted in an informal and compromising position while she was on a cruise.

In the book “Queen of the World,” royal author Robert Hardman detailed an incident that took place while the Queen was on board the Royal Yacht Britania years ago. At that time, Her Majesty was asked to participate in an elaborate pantomime.

“The diplomat Roger du Boulay and his wife joined the Yacht for a week in 1974 during his years as Resident Commissioner of the New Hebrides in the Pacific. The du Boulays were astounded one night when dinner was followed by the ship’s entertainment – an elaborate pantomime – in front of the Royal Family and the crew with the Queen acting as a wardrobe assistant,” he said.

According to Hardman, the equerry assumed the role of a Polynesian beauty, and he sat on the floor while the Queen was kneeling down on the ground. The equerry was stripped to his waist, and Her Majesty fitted a brasserie on him. The royal author said that it was such an extraordinary sight.

Meanwhile, Hardman discussed another informal moment on the yacht that also involved the monarch. He said that informality would usually go a long way on the Royal Yacht Britannia but it also had its limits.

“John Gorton, former Prime Minister of Australia, later recalled one beach barbecue with the family during a 1970 tour of Australia, when the royal party decided it was time for a swim. Princess Anne was thrown in and then Prince Philip,” he said.

Gorton was sitting next to Her Majesty and he was just about to throw her into the water but she looked at him and there was something about the way she looked that told him he shouldn’t even attempt to do it. At the end of the trip, it was only the monarch who managed to stay dry.
