Watch: Harry’s book blindsides the royals and torpedoes all hope of reconciliation
Prince Harry's decision to release a tell-all memoir in the same year his grandmother celebrates her Platinum Jubilee has thrown his invitation to the events into question.
The Queen will mark 70 years on the throne in 2022, and huge events are being planned to mark the occasion, including the return of the full-scale Trooping the Colour and a parade through London.
It had been assumed that as members of the family, Prince Harry and Meghan Markle would be invited to return to the UK to attend, but Harry's memoir release has sparked speculation they won't be welcome.
The Sun quoted royal sources who suggested it would be "inconceivable" for them to be part of the 2022 celebrations.
However, Joe Little, managing editor of Majesty Magazine, told Yahoo UK: "News of this book deal is unlikely to accelerate the reconciliation process that Charles, William and Harry are now going through, but there's nothing yet to suggest that their fractured relationship can't be fixed.
"The Queen is not mean-spirited, so my guess is that the Sussexes will still be invited to her Platinum Jubilee celebrations next summer. If the invitation has already gone out, then it won't be withdrawn.
"Regardless of all that has gone on in the past 18 months, there will continue to be a (supposedly) private dialogue between Harry and his grandmother."
Royal expert Ingrid Seward told the MailOnline: "It's also very thoughtless that this should happen in the Queen's Platinum Jubilee year. Sadly, it seems Harry hasn't thought about the consequences for his family."
Harry's book is tentatively scheduled for release in late 2022, and with most of the Queen's celebrations planned for the bumper bank holiday in June, there might not be much overlap.
However the book could be serialised, as royal biographies often are, ahead of release, which would mean there could be excerpts in the public domain earlier than the official release.
The Queen has previously referred to Harry, Meghan and Archie, before the birth of Lilibet, as "much-loved" members of the family, despite the revelations and allegations made in the Oprah Winfrey interview and later comments.
According to The Times, news of the book was met with "big sighs" inside the palace.
Charles was said to be surprised, though the Duke and Duchess of Cambridge were reportedly "neither shocked nor surprised".
A spokesperson for Prince Harry said he did not have to seek permission for the project, but that he did speak to his family "very recently".
In the 1950s, both the Duke and Duchess of Windsor wrote their memoirs, and the Queen retained some form of relationship with her uncle.
The duke, who had been King Edward VIII before he abdicated, was invited to the investiture of the Prince of Wales in 1969, and the Queen visited him when he was in London for surgery toward the end of his life.
That could be good news for Harry, who has been careful to make sure his love and admiration for his grandmother is clear.
Buckingham Palace won't release details of the invitations for the Jubilee until closer to the date of the events.
