The Duchess of Cornwall won't be attending a memorial service for the Princess of Wales.
She has pulled out of the ceremony in London on Friday to mark the 10th anniversary of Diana's death.
Camilla was invited by Princes William and Harry and had initially accepted.
But she has decided not to go, fearing her appearance would divert attention from the purpose of the occasion.
Royal Biographer Robert Lacey thinks she made the right choice.
