This Morning: Prince Harry talks about Prince Philip new documentary
The expert believes that as the US travel ban is no longer in place, it cannot be used as an “excuse” by the Duke and Duchess for not visiting the Queen. Following a recent announcement, the US will lift its travel ban on the UK from the start of November.
This means that Prince Harry and Meghan Markle, who are both based in California at present, can visit the Queen in England. Again.
Harry, 37, and Meghan, 40, have not returned to visit the Queen at any point together since they had made the journey over to America for a new life.
However, speaking to the Sun, royal expert Adam Helliker believes that a return from Meghan and Harry together is “imperative for family unity”.
Mr Helliker believes that if Prince Harry and Ms Markle were to return home, the trip would be “a private family visit" and "very low key”.

During this visit, Mr Helliker believes that the couple would only visit key royals, including Prince Charles, Camilla and Prince William.
Mr Helliker told the Sun: "I think it's imperative for family unity that the whole family comes over because, to put it bluntly, the queen is getting older and these won't arrive too often again.
"I think Harry will feel particularly guilty if she doesn't see the great-grandchildren she's not seen much of - or the great-granddaughter she's not seen at all.

"I think if they're going to try to patch things up - and we all hope they will work to increase what remains of the unity between them and the family - then I think it's paramount that they start planning a trip for maybe early December.
“I doubt obviously they want to be restricted by spending any Christmases at Sandringham, but maybe a mid-December pre-Christmas trip to say hello to the family.
"For Harry, those family ties - until he was encouraged by her to break them - were really important."

Mr Helliker also believes that following the bombshell Oprah Winfrey interview with Prince Harry and Meghan Markle, both sides of the now divided family are “striving for reconciliation”.
In the bombshell interview, the Sussexes explained a revealing moment between them and a “family” member.
The “family” member in question was alleged to have asked what colour their unborn son Archie would be, as well as “what that would mean or look like”.
Speculation has been rife that Prince Harry and Meghan Markle have been planning to return to the UK to ensure that their son Archie is christened.

However, Mr Helliker does not think this is likely to occur.
Mr Helliker added: “They seem to have very fixed views about the privacy of family occasions.
“I think having the christening in the UK will be putting too much pressure on them.
“And I think Meghan will be putting her foot down and say no we don't want an international circus.
