When this comes to an end on Monday, there is speculation surrounding new titles for Archie, three, and Lilibet, one.
In line with tradition, it is expected that the two youngsters will take on Prince and Princess titles. The royal tradition emerged in 1917 during King George V's reign whereby the King introduced a new rule allowing children and grandchildren of the monarch to claim titles.

Archie and Lilibet aren't the only members of the royal family poised for potential change. Prince Edward could take on the late Prince Philip's title as the Duke of Edinburgh while his wife Sophie Wessex may subsequently become The Duchess of Edinburgh – a courtesy title which was held by the Queen from her wedding in 1947 until her accession in 1952.
