The Princess of Wales and Duchess of Sussex are "not known" to have exchanged words during the Sussexes' stay in the UK, sources have said.
In the wake of the Queen's death, Kate and Meghan have appeared in public several times together, including at the late monarch's state funeral and committal service. They also came together with their husbands, feuding brothers Prince William and Prince Harry, to view floral tributes left for the Queen at Windsor Castle and to greet wellwishers. Much has been made over the sisters-in-law's relationship after reports that Meghan made Kate cry in the run-up to her wedding in 2018.
But in her bombshell interview with Oprah Winfrey, Kate was publicly singled out by Meghan for allegedly making her cry.
And despite the pair both staying in Windsor since the Queen's death, sources have said the pair were "not known" to have exchanged words throughout the whole period that the Sussexes were in the UK.
It comes after insiders also said that William's temporary truce with his estranged brother will remain until after Harry publishes his memoir.
The Prince of Wales and the Duke of Sussex stood shoulder to shoulder during a solemn procession from Buckingham Palace to Westminster Hall last week, guiding Her Majesty on a final journey before her lying in state.
But in a striking picture taken on the day of the Queen’s funeral, the divisions in the family were laid bare as Prince Harry and his disgraced uncle Prince Andrew walked on the outside of the King and his heir.
Despite the family coming together to honour our late monarch, including two vigils by the Queen's children and grandchildren, where Andrew and Harry were given special dispensation to wear their military uniforms, insiders have revealed that their relationship with the rest of The Firm still remains fractured beyond repair.
Royal sources have revealed that regardless of the display of harmony between the former "Fab Four" of the brothers and their wives, the princes did not plan to meet throughout Harry’s time in the UK.
William, 40, and Harry, 38, reportedly had just one meeting last Thursday when they shared a brief chance encounter.
The Prince of Wales was returning to Windsor after collecting his children Prince George, Princess Charlotte and Prince Louis from school. Harry and Meghan, 41, were in their car as the brothers drove past each other, but then stopped, reversed, wound down their windows and chatted, according to the Sunday Times.
One royal insider said: "The family continue to be in mourning and are now finally being allowed to grieve for the Queen away from the gaze of millions.
"However, any talk of a truce between the Prince and the Duke would only be temporary.
"There is still a serious amount of distrust in the air and there hasn’t been any cause for that to change.
"The feeling is very much that there is little point in pursuing a repair in relations until all the cards are on the table.'
The Duke of Sussex's memoir, which was due to be released in December, is set to be delayed because of the royal mourning period.
It is now likely to be published next year. Senior royals including the King and Prince William are said to be "“increasingly uneasy" about the content of the book.
Royal watchers had been hopeful of a resolution between the two brothers when they reunited in grief to pay tribute to their beloved grandmother last week. But their relationship remains near to rock bottom, according to sources.
In a moving scene reminiscent of past happier times for these once inseparable siblings, the images of the Prince of Wales and Duke of Sussex once more standing beside one another warmed a nation grieving for their lost Queen.
Sources last night, however, suggested that any hint of a rapprochement between the couples was "very unlikely".
