Prince William and Prince Harry could reunite for a significant event marking 30 years since Princess Diana's death, according to royal author Robert Jobson. The milestone anniversary falls next year, with the late Princess of Wales having died in a car crash in Paris on August 31, 1997.
Diana's death had a profound impact on both the Prince of Wales and the Duke of Sussex, who walked behind their mother's coffin aged 15 and 12 respectively. The brothers are reportedly not on speaking terms following Harry's claims against the Royal Family.
Royal author claims brothers 'have to be on the same stage'
Speaking to Hello! Magazine, Mr Jobson said: "The 30th anniversary is going to be quite significant, I think. The ownership of the Diana legacy is something I think Harry has been really pursuing; he's been to Angola, he's done more stuff in landmines as well."
He added: "There's going to be a moment where there has to be some form of arrangement for the 30th anniversary of Diana's death. How can they not be together?"
"They have to be on the same stage. I think that we're going to see more of Harry trying to take over the ownership of Diana's legacy, which is bound to irritate his brother," Mr Jobson continued.
Earl Spencer announces memoir in Diana's memory
The late Princess of Wales died aged 36 in Paris in 1997. Earlier this week, her brother, Earl Charles Spencer, announced he is publishing a memoir, Swan Song, in her memory.
Speaking of William's likely reaction to the announcement, Robert said he must "be feeling slightly aghast". It has been reported that William was with his father, King Charles, at Balmoral Castle in Scotland when news of the return was made public.
Harry and Meghan return to Britain
The royal expert added: "The prodigal son coming back will be difficult for him. Harry's move puts pressure on him to act in a more pragmatic way."
The comments come as the Duke and Duchess of Sussex returned to Britain earlier this week, more than six years after they relocated to the US. Harry, Meghan Markle, Prince Archie and Princess Lilibet flew into the country on a private plane from California shortly before midday on Wednesday, landing at Birmingham Airport. The family were said to have travelled on a Bombardier Global Express XRS luxury long-range business jet for the overnight flight.
It is understood there will be no change to Harry and Meghan's role and status as private individuals and non-working members of the Royal Family.
