Only hours after King Charles III's proclamation, many headlines focused heavily on a surprise public appearance by Prince William and Prince Harry, who were joined by their wives Catherine and Meghan outside Windsor Castle.
It was the brothers' first public appearance together since the death of their grandmother, Queen Elizabeth II.
It was also the first time the two couples had been seen together since Harry and Meghan, the Duke and Duchess of Sussex, made a highly publicised withdrawal from royal life.
