Young Royals Join Coronation Procession.

Prince George, Princess Charlotte, and Prince Louis are expected to take part in the coronation procession from Westminster Abbey to Buckingham Palace behind their grandfather, King Charles, and step-grandmother, Queen Camilla, in procession to Buckingham with other members of the royal family. The attendance of Louis, who will be 5, was up in the air. Their cousins, Prince Archie and Princess Lilibet, have reportedly not yet been invited to the coronation.
