Prince Archie and Princess Lilibet, the children of the Duke and Duchess of Sussex, have been given new names - Archie Sussex and Lilibet Sussex.
The decision to use alternative surnames breaks a tradition established in 1960 that future heirs of Queen Elizabeth II would be named Mountbatten-Windsor.
The rebrand to Sussex is a way to showcase the charity work of the couple and unify the family under a single surname.
