Kate Middleton decided to stay out of the royal drama on Saturday - according to experts.
The Princess of Wales was spotted making a swift head turn gesture from Queen Camilla as she gave King Charles a "stern pep talk" at his birthday parade, a body language expert has claimed.
On Saturday, pomp and pageantry were on display during the Trooping the Colour military spectacle where the most prestigious regiments in the British Army honoured the monarch by parading to mark his birthday.
