The children of Prince Harry and Meghan Markle are technically a prince and princess following the death of the Queen, but their titles remain unchanged.
As the grandchildren of the reigning monarch, Archie and Lilibet Mountbatten-Windsor are entitled to HRH titles. However, the new order of succession published on the Royal Family's website on Saturday shows the children are still titled as Master and Miss.
It has not been confirmed by their parents or Buckingham Palace whether they will use the titles, although the update reflected the new role of Prince William after the heir was named the Prince of Wales.
