Given that several key royal engagements take place from March until July, Meghan, Harry and Archie could remain in Britain for several weeks.
The coronavirus pandemic and Meghan and Harry’s withdrawal from royal life mean Archie has not seen much of his royal cousins – Prince George, Princess Charlotte and Louis.
The young royals could all be reunited next year at the Queen’s official birthday parade Trooping the Colour that traditionally takes place in May.
There is also a chance Harry will want to be back home to mark his grandfather Prince Philip’s 100th birthday.
