We still don't know whether Prince Harry and Meghan Markle will attend King Charles' Coronation - but the bookies reckon the chances are sinking by the day.
The Duke and Duchess of Sussex have been invited to be part of the congregation gathered inside Westminster Abbey on May 6.
However, it's been reported that their children, Prince Archie and Princess Lilibet, have not been asked to come to the momentous event - with the added complication of it falling on the former's fourth birthday.
There is a lot of tension within the Royal Family due to the shock eviction from Frogmore Cottage, Harry's revealing book Spare and the couple's controversial Netflix docu-series.
The strained relations make a visit from Harry and Meghan far from certain, and bookmakers believe the likelihood of them coming to London on that day is decreasing.
SuperBettingSites have looked at the aggregated odds from a number of bookmakers - and discovered the downward trend.
They are both still odds on to attend the Coronation, but they are convinced there is more chance of Harry going on his own.
The aggregated bookmaker odd of Harry attending are 1/4, while a no-show is out at 11/4.
In percentage terms, this sees the market predicting an 80% implied probability that the Duke of Sussex will go to the coronation.
For both Harry and Meghan to rock up its 1/2 - and a lack of appearance from the pair is 9/4.
In percentage terms, this sees the market predicting a 66.7% implied probability that Prince Harry and Meghan will go to the coronation as a couple.
While these figures do not appear to be catastrophic, they do show a downward trend in the odds.
Marcus Goldberg, odds analyst at SuperBettingSites, says: "When the coronation date was officially announced on October 11, 2022, the bookmakers' odds for Prince Harry and Meghan Markle attending the event were higher (1/6) compared to the current odds (1/2).
"The reason for this is that a lot has happened since then, including the release of Harry's memoir, Spare, which contains harsh criticism of senior members of the royal family.
"What is more, the Duke of Sussex insists on a face-to-face meeting with his father, which is unlikely to happen anytime soon.
"King Charles III has waited for the coronation his entire life and May 6 is not the time for reconciliation with his younger son."
Despite being the grandchildren of the new King, it is believed that Archie and Lilibet have not been invited, with sources citing that the children are "very young".
Charles' accession to the throne means the youngsters, who lives in California with Harry and Meghan, have taken up their titles as Prince and Princess.
An insider told OK! that a major sticking point was how the Sussex children Archie, three, and one-year-old Lilibet were to be included on the day.
But the source explained that their inclusion in the ceremony has "never been a bone of contention" because small children don’t attend royal events of this scale "due to restlessness and tantrums".
According to royal historian and author Dr Tessa Dunlop, it would be "odd" if Archie has not been invited to the event.
She told True Royalty TV's The Royal Beat: "If you look at the footage of the 1953 Coronation, who was very prominent, albeit briefly? Prince Charles. He was four.
"Archie on his fourth birthday is definitely not too young to attend the coronation. And if you want Meghan there, you need to invite her son."
It's believed that Harry will only come if he gets a face-to-face meeting with his father and brother.
According to sources, Harry wants a summit with King Charles and Prince William to discuss their issues.
An insider told The Mirror: "Harry has been very clear and his position hasn't wavered – he isn't going to come if he feels the atmosphere will be as toxic as it was during the Queen’s Platinum Jubilee and funeral.
"He's said he wants to reconcile with his family and it’s their call, but so far nothing has changed."
