Camilla, the Duchess of Cornwall, suffered an attack of vertigo during the Trooping the Colour ceremony over the weekend. The duchess - the wife of Britain's Prince Charles - could barely be seen when she joined the British Royal Family on the balcony of London's Buckingham Palace to watch the event on Sunday, as she was standing well away from the edge.
While she would normally be expected to take pride of place alongside her husband at the front, Camilla, who turns 60 next month, cowered behind the group.
A source told Britain's Daily Mail newspaper: "She has awful vertigo and can't go to the front without feeling ill, and the balcony does have a very low balustrade."
The Trooping the Colour parade is based on a long-standing tradition in the British military first performed during the reign of 17th century monarch King Charles II.
The ceremony involved regiments of the Commonwealth and the British Army 'trooping' (marching) their 'colors' (flags) through the ranks so the soldiers could recognize what the flag for their individual regiment looked like.
The tradition is now used to mark Queen Elizabeth's official birthday - she actually turned 81 in April - and is known as the Queen's Birthday Parade.
