Prince William and Harry AREN’T offering an olive branch to each other in days before Princess Diana service, pal claims

, joint friends of both siblings don't believe they will mend their rift, despite being in the same country at the same time.

One said: "Neither are offering an olive branch.

"I fear it will be the same as at Prince Philip's funeral, a nod of recognition and that's about it."

Another source admitted to being worried that "on the day it will be difficult to separate the statue from the occasion, which is now loaded with all sorts of unwelcome baggage."

But one mate predicted there will be no sign of lingering tension between the battling bros on the big day, when "all will be lovely".

It comes as:

• The Queen was spotted driving towards Frogmore Cottage after her grandson touched down at Heathrow
• A royal expert claims Meghan and Harry 'want money for doing very little in return'
• Harry and William have been forced to slash the guest list for the unveiling of a new statue to commemorate their mother
• The Duke and Duchess of Sussex have been slammed by Dumbarton locals - after rejecting it for Archie over the word 'dumb'
• And the couple say they weren't being misleading when they told Oprah they'd been 'cut off' by the Royal Family after Megxit

Just last month the Duke of Sussex revealed that returning to London was a "trigger" for him after Diana's death, while he tackled his personal traumas in an on-screen therapy session.

In the doc, The Me You Can't See, the royal said he has a "hollow empty feeling of nervousness" whenever he arrives in the capital and admitted he feels "hunted and helpless" while he's there.

When questioned by his therapist about how it makes him feel, Harry said: "[Like there] is no escape. There is no way out of this."

He was last in the UK for Prince Philip's funeral.

But William and Harry were "at each other's throats" moments after they were out of sight of the press, according to new bombshell claims.

Robert Lacey - the author of explosive book Battle of Brothers, which looks into the feud between the pair - says a row broke out as soon as they stepped inside Windsor Castle.

Millions of royal fans around the world had hoped for the brothers to reconcile after photographers captured images of them chatting together after the service in April.

It was understood Charles had sent away the funeral cars to allow his sons the chance to talk face-to-face for the first time since Harry's move to LA.

But Mr Lacey said efforts to encourage the men to make their peace were to no avail - and friends "have been despairing over the searing animosity - the sheer uncompromising, bloody-minded anger - between the two."

Meanwhile, one key family member won't be about for about for a catch-up with Harry.

In an unfortunate clash of diaries, Prince Charles is in Scotland ahead of the unveiling of Diana's statue.

A source said: "Charles will leave the boys to it. Harry will need to quarantine for at least five days when he lands in England, most likely at Frogmore Cottage in Windsor.

"Charles has made it quite clear he will not be around beyond that because he is going to Scotland. There is no planned meeting between the three of them.”

The brothers have been communicating by text amid a bitter fallout.

Another source said: "There have not been any personal chats or proper talks, just a very brief and minimal exchange of text messages.

“The relationship is still very much strained and there’s no sign yet that there will be any sort of coming together any time soon.”

Among those attending the statue unveiling will be members of the statue committee, sculptor Ian Rank-Broadley who created the artwork, and garden designer Pip Morrison.
