Prince Harry and Prince William put their late mum Diana "at the heart of the Royal Family" despite their ongoing rift, a royal author has said.
The two brothers came together last week to unveil a statue for the Princess of Wales at Kensington Palace's Sunken Garden on what would have been her 60th birthday.
Robert Lacey, author of the book "Battle of Brothers", said that during the years after their mum's death, Harry and William have always found ways to keep Diana's legacy alive.
He told People: "In the past quarter of a century, they have placed their mother right at the heart of the royal family."
Mr Lacey added this is "something the Queen and Prince Charles certainly wouldn't have done", but the two brothers "have done it together".
The royal author and historian said Harry and William have admitted there are differences between them, but found a "constructive way of dealing" with them.
He added it was clear that the two brothers were "acknowledging more important things and doing that in a way that warmed everyone's heart" at the ceremony on July 1.
They were seen chatting and joking during the event - and even released a joint statement to honour their mum.
The Duke of Sussex and the Duke of Cambridge 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.
"Every day we wish she were still with us."
In 2017, they commissioned the statue to mark Diana's legacy and life, eventually selecting sculptor Ian Rank-Broadley, whose effigy of Queen Elizabeth has been used on British and Commonwealth coinage, as its designer.
According to body language expert Judi James, the pair showed some signs of inner tensions but looked relaxed.
Writing for the Mirror, she said: "They could have opted for a chilly distance with just a few curt words exchanged but instead William and Harry took the decision to show a display of unity with the eyes of the world on them at the unveiling of their mother’s statue.
"There were clearly some signs of inner tensions but the self-comfort ritual that was Harry’s wedding ring fiddling and William’s jacket-patting and touching were all normal traits for both brothers.
"There were jokes with all of the guests and it was Harry’s more active eye-checking of his brother that suggested he was keen to build some rapport.
"There were moments of eye contact between them and with no obvious changes of eye expression or face-dropping that might suggest suppressed enmity.
"Instead Harry’s wide, horizontal grin looked so much like the old, playful Harry before the rift and William’s rounded cheeks and rather more puckered lips suggested genuine pleasure."
