The Sunday Times reported Prince Philip's nickname was confirmed by Robert Lacey, the monarch's biographer, who said: "Yes, I've heard that is how he will sometimes refer to her."
The question revolves around a throw-away line in a new film about the royal family, "The Queen," which is set in the tumultuous days after the death of Diana, Princess of Wales, in August 1997.
The name, "Cabbage," the Times ventured, may stem from the French term of affection "mon petit chou", which literally means "my little cabbage", although it can also be translated as "my little pastry puff."
