Prince William and Kate have struck a "truce" with Meghan and Harry but the trust is "gone", a royal insider has claimed.
Prince and Princess of Wales and Duke and Duchess of Sussex will tonight attend Queen Elizabeth II's vigil beside her coffin in Westminster Hall.
The royal brothers will stand at the head and the foot of the catafalque to pay their respects to their beloved grandmother, who died aged 96 last week at Balmoral Castle in Aberdeenshire, Scotland.
It's said Harry and William now have a "current truce" struck through immense grief.
But an insider told The Telegraph: "It’s really hard to spend time with someone, or even to speak openly, when you know they’re writing a book about you and giving interviews. The trust is gone right now."
During King Charles III's first address as sovereign last Friday, the 73-year-old monarch expressed “my love for Harry and Meghan, as they continue to build their lives overseas”.
And even after Harry and Meghan decided to step back from royal life in January 2020, Queen Elizabeth II always insisted that they remained “much loved members of the family”.
Other relatives, including Peter Phillips, Zara Tindall, Princess Beatrice, Princess Eugenie, Lady Louise Windsor and James, Viscount Severn, will also be at the vigil tonight.
King Charles personally asked Harry to wear his Blues and Royals uniform at the poignant ceremony, which the Telegraph claims is further evidence he wants his sons to bury the hatchet for good.
A former Royal aide told the publication: “It’s simply not the King’s style to do anything that would alienate either of his children. He loves them both deeply and has been devastated by everything that has happened.”
Harry and Meghan, despite being "non-working royals", took part in Wednesday’s royal procession from Buckingham Palace to Westminster Hall and will play a similarly prominent part in Monday’s final farewell at Westminster Abbey and St George’s Chapel, Windsor.
The couple is expected to make a swift departure back to their £11 million mansion in Montecito, California, to be reunited with their children Archie, three, and one-year-old Lilibet, on Monday evening.
In the wake of the Queen's death, Meghan has shelved her Archetypes podcast for six weeks and cancelled a planned appearance on The Tonight Show Starring Jimmy Fallon.
Martin Townsend, former editor of the Sunday Express and current PR guru, said: "Charles is the King and therefore automatically commands much more support than he used to. That support has only increased because of the remarkable way he has led a nation in mourning.
"So if Harry and Meghan choose to attack all that now - they are going to look completely out of step. The trouble for the couple, however, is that they only seem to be able to gain publicity for their salvos against the royals. Once that stops - what have they got left?”
