Writing in his latest exclusive column, Yahoo's Royal Executive Editor Omid Scobie says any claims about their attendance are speculative, and the couple "can't make a decision" about whether to attend without an invite.
The presence of the Duke and Duchess of Sussex at the celebratory event on 6 May has generated a significant amount of speculation in recent weeks following a difficult few months for the Royal Family as they transition away from the stability of Queen Elizabeth’s long reign.
In November last year, the racism row involving Lady Susan Hussey and charity campaigner Ngozi Fulani engulfed the royals.
The Sussexes claimed Camilla, the Queen Consort, leaked stories to the press about the couple in what Harry alleged was an effort to rehabilitate her own public image after being known for so long as the "other woman" in Charles and Diana's marriage.
Harry also alleged that his brother physically attacked him during a 2019 encounter, in which William "parroted the press narrative" about Meghan. The Palace has not responded to either claim.
By Harry’s own admission, his relationship with his brother and father has grown cold. Speaking in an interview promoting Spare with ITV’s Tom Bradby, he said he wanted to get his “brother back” but that he no longer recognises his family members — and acknowledged “they probably don’t recognise me”.
Equally, he wrote in the introduction to his memoir that it was an attempt to be understood on his own terms not only by the public, but also his father and elder brother. And in an interview with The Telegraph, Harry said he had held back on revealing certain things in his memoir to allow for the possibility of reconciliation with his family.
While some reports have said the couple will be invited to the coronation, Yahoo UK understands that the Sussexes have not been invited.
Scobie writes: "No one, no matter how well-sourced, knows their plans right now — the couple have yet to be invited and can’t make a decision, or plans, until that happens."
Yahoo understands that invites will be going out to guests "in the coming days" but there is no word as to whether Harry and Meghan are on the list.
The prospect of a reunion in May would be the first time the three would have been together since Harry's claims and the first time since they gathered for Queen Elizabeth II's funeral in September.
King Charles III's coronation will take place on the morning of Saturday, 6 May.
It will take place at the historic Westminster Abbey, where the Coronation Ceremony has taken place for the last 900 years.
Once the solemn, religious service is completed, they will process back to Buckingham Palace accompanied by other members of the Royal Family.
The day will end with an appearance by the King and his family on the balcony of Buckingham Palace.
