Harry, 37, and Meghan, 40, have not been to the UK together since they left the country for a life at the lake last year.
But now, following the birth of their daughter, Lilibet, in June, royal writer Adam Helliker said it was “obligatory for family unity” that brood Harry’s return to his homeland.
Mr. Helliker told the Sun: “I think getting the whole family together is essential to family unity because, to put it bluntly, the queen is getting old and they won’t come around very often again.
“I think Harry will feel especially guilty if he doesn’t see grandchildren he doesn’t see much or great-grandchildren he never sees.
“I think if they’re going to try to fix things – and we all hope they will work to increase what’s left of the unity between them and the family – then I think it’s very important that they start planning a trip maybe in early December.
“I honestly doubt they want to be restricted from spending any Christmas in Sandringham, but maybe a pre-Christmas trip in mid-December to say hello to the family.
“For Harry, those family ties – until he encouraged them to break up – were really important.”
Bombshell said both sides would “endea for reconciliation” following the conclusions from the Oprah interview.
