Although a royal expert claims it is "sad" Prince Archie and Princess Lilibet are growing up away from their royal cousins, it is believed a home base in Portugal might strengthen relationships between Prince Harry, Meghan Markle and the Royal Family and even help put an end to the estrangement between the Sussexes and the rest of the royals.

has been seen by some as a symbol that the couple wish to integrate European life into the lives of their children.

Former BBC royal correspondent, Jennie Bond, told : "It may well be that with Donald Trump back in the White House, Harry and Meghan might spend more time in their Portugal house, at least in the school holidays."

Jennie described the sadness of Archie and Lilibet being "estranged" from Harry's relatives. She explained: "How curious, and sad, it will be for Archie and Lilibet if they grow up knowing they are part of one of the most famous families in the world - and yet they are estranged from almost all of them.
