Princess Diana's biographer claims she would be 'disappointed' by William and Harry's rift

Royal biographer Andrew Morton claims Princess Diana "would've been very disappointed" by the reported rift between her sons Prince Harry and Prince William.

Morton rose to fame in 1992 after writing an explosive tell-all about the Princess of Wales, which she had secretly contributed to.

Appearing on UK breakfast program Lorraine this week, he spoke of the heartbreak he believes Diana would have felt over the 'rift' between her sons, particularly following Harry's decision to step back from his royal duties.

"Diana confided everything in you, she told you absolutely everything," the host said, asking Morton what Diana would have thought about her sons' strained relationship.

Noting Diana stepped back from royal life in her own way after separating from Prince Charles, Morton said he hoped her spirit would bring the royal brothers back together.

"Hopefully the spirit of Diana can help some kind of reconciliation when they unveil her statue at Kensington Palace gardens this summer," he shared.

Morton appeared on Lorraine to discuss his new biography Elizabeth and Margaret, which comes almost 30 years after his groundbreaking biography Diana: In Her Own Words.

William and Harry are scheduled to reunite for the first time in a year at the unveiling of a statue of their mother on July 1, what would have been her 60^thbirthday.

The event is expected to go ahead regardless of the fallout of Harry and Meghan's interview with Oprah Winfrey.

Morton also revealed Diana had been "thinking of living in Malibu", which is near Montecito, where Prince Harry and Meghan Markle currently reside.

Despite the tensions that have arisen as a result of the royal exit, Morton says Diana "would've totally understood Harry's decision to step back."

The Duke and Duchess of Sussex resigned as working members of the royal family in January 2020.

William, 38, reportedly told a friend at the time, "I've put my arm around my brother all our lives and I can't do that anymore; we're separate entities. I'm sad about that.

"All we can do, and all I can do, is try and support them and hope that the time comes when we're all singing from the same page."

However, a rift has long been rumoured between the pair.

Omid Scobie and Carolyn Durand's tell-all book Finding Freedom claimed tension between the brothers was "inevitable".

When Harry first introduced his brother to Meghan Markle, William is claimed to have said, "Don't feel like you need to rush this. Take as much time as you need to get to know this girl."

British author Robert Lacey made the rift the subject of his 2020 book Battle of Brothers.

In a press release, Lacey said of the book: "These two brothers - once inseparable and now separated by much more than mere distance - have been acting out the contradictions that go back into their childhoods and even before that: into their parents' ill-fated marriage.

"We have seen conflicts between heir and spare in every recent generation of the royal family — but nothing so profound as this."

William is said to be "livid" over Harry and Meghan's claims of racist conversations within the royal family, mentioned during their interview with Oprah.

"William and his father have long spoken about racism and mental health," a royal source told The Sun.

"For them to be accused of being racist is deeply upsetting and wrong."

Harry and Meghan told Winfrey comments had been made regarding the colour of their son's skin before he was born, but did not name who was responsible.
