Meghan Markle has "no desire" to come to the UK for Trooping the Colour as she and Prince Harry are set to miss out on the major royal event, an expert has said.
The first King's birthday parade of Charles' reign is due to take place tomorrow with a huge turnout of royals set to appear.
It will see 1,400 soldiers, 200 horses and 400 musicians, as well as members of the Royal Family who will ride on horseback and in carriages processing from Buckingham Palace and down the Mall to Horse Guard’s Parade.
After a military service there, the royals will head back to the palace and watch a huge RAF flypast from the balcony.
Harry and Meghan attended the late Queen's final Trooping the Colour last year - although were not permitted to appear on the balcony as it was limited to working royals only.
And this year, they are not expected to attend at all - despite it being the first poignant ceremony for Harry's father Charles.
The Mirror's royal editor Russell Myers explained: "As the final touches are being made to the King’s first Trooping the Colour, one or two names not on the guest list are the Duke and Duchess of Sussex.
"After Prince Harry ’s whirlwind 30-hour trip to the UK it is understood there has been no contact between the Duke and his father or brother, despite his recent trip to London.
"The Sussexes’ absence will come as no surprise but the poignancy of the no-show will be noted as yet another missed opportunity for Harry and his family to sit down and start a new chapter in their relationship.
"It seems clear from sources across the pond, that Meghan as well as not being eager to attend the Coronation, had no desire to make the trip for the family gathering this weekend, in celebration of the monarch’s birthday.
"Aside from the King’s actual birthday in November, it’s hard to see when any such meeting would take place ahead of Christmas.
"Palace sources suggest once again an invitation would be extended to the Sussexes as a courtesy, whether they accept is an entirely different matter."
For Charles and Queen Camilla's Coronation last month, Harry attended the ceremony solo before quickly dashing back to his family.
Meghan stayed at home in California with their children Prince Archie, who celebrated his fourth birthday on the same day, and Princess Lilibet.
