On Thursday, a statue of the late Princess Diana was unveiled at Kensington Palace by her two sons, Prince William and Prince Harry. Now, a royal expert is speaking out to claim that there is “no way” that Queen Elizabeth would have ever chosen to put this statue up herself.

“There’s no way the Queen would have put up a statue for Diana,” royal expert Robert Lacey told True Royalty’s The Royal Beat. “Obviously no way Charles would have put up a statue for Diana, so this is them – it’s the new generation of Spencer taking over. There’s not a Windsor in sight, it’s that side of the family.”

William and Harry commissioned the statue back in 2017 in the hopes of honoring their late mother.

“It has been 20 years since our mother’s death and the time is right to recognize her positive impact in the UK and around the world with a permanent statue,” they said at the time. “Our mother touched so many lives. We hope the statue will help all those who visit Kensington Palace to reflect on her life and her legacy.”

While the two brothers were the only royals to attend the event, it was also attended by Diana’s brother, the Earl Spencer, as well as her sisters, Lady Jane Fellowes and Lady Sarah McCorquodale.

The statue was designed by British sculptor Ian Rank-Broadley, and was placed in the Sunken Garden at Kensington Palace, which was Diana’s favorite spot.

While speaking to the attendees at the small event on Thursday, the brothers said, “Today, on what would have been our mother’s 60th birthday, we remember her love, strength and character — qualities that made her a force for good around the world, changing countless lives for the better.”

Prince Charles, Diana’s ex-husband, also opted out of attending the event.

“He does find it terribly difficult,” an insider told Vanity Fair. “These moments have the potential to resurface old wounds, and it brings back memories for him; happy, sad, regretful. Since Diana’s death, he has felt it’s best to keep those memories to himself and leave his sons to it.”
