King Charles III and Princess Anne are just 21 months apart in age.
Anne more than held her own with her big brother.
That closeness was on display at a Buckingham Palace ceremony a few days before the 2023 Trooping the Colour.
The Blues and Royals is a regiment in the Household Cavalry, and Princess Anne is their honorary Colonel.
Both Charles and Anne will be riding on horseback for the event.
We love to see the siblings together doing their royal duty!
