He may be the heir to the throne but Prince Charles was given a sharp reminder by the Duchess of Cornwall yesterday as to who's the real boss.
Camilla, a mischievous glint in her eye, jokingly brandished a kitchen knife at him and warned: "Behave yourself!"
Charles gave a mock grimace and eventually replied, "Now listen here..." - but only after his wife had carefully put down the 8in Japanese-style blade.
The pair were presented with a set of hand-forged knives, a gift from the Australian government, as they visited a vineyard on the first day of their official tour of Australia.
