Prince William and Kate Middleton "felt a sense of relief" when Prince Harry and Meghan Markle departed following the Queen's funeral, according to reports.
Harry and Meghan are expected to return to the USA soon as the nation's period of national mourning nears its end.
The Duke and Duchess of Sussex happened to be in the UK when the Queen died and extended their stay to mourn the Prince's grandmother with his family.
Although Harry has stepped back from royal duties, he and Meghan took their place alongside his family for the ceremonies of the Queen’s state funeral on Monday and joined William and Kate in meeting members of the public at Windsor in the days after the Queen's death.
But the new Prince and Princess of Wales are said to have 'felt relief' when Harry and Meghan left in the hours following Monday's funeral.
Vanity Fair royal correspondent Katie Nicholl said: "After Harry announced their departure, William summoned aides to address the future, in what has been referred to by some in William’s circle as the “Anmer Summit.”
"But William and Kate also felt a sense of relief, that “the drama was gone” when Harry and Meghan left, as a source told me. To this day, William still cannot forgive his brother."
It comes as a source close to the Royal Family told US Weekly that Harry and Meghan are anxious to return home to the US to see their children.
“Meghan and Harry are preparing to return to Montecito almost immediately after the funeral, where they’ll be reunited with Archie and Lilibet after being separated for over two weeks,” the insider said.
They also noted it was the “longest amount of time” the couple had spent apart from their children.
The Duke and Duchess of Sussex, who are parents to three-year-old Archie and Lilibet, who is 15 months old, headed to Europe on September 4.
They had initially planned to spend less than a week across the pond, speaking at a series of philanthropic events.
However, they extended their stay after the Queen died on September 8 and have been reunited with the Royal Family to grieve ever since.
The insider said: “They’ve missed the kids like crazy and have been FaceTiming them every day, but can’t wait to see and hold them again after a poignant few weeks.”
Harry rushed to be by the Queen’s side after being told her health had declined.
A spokesman for the King said: "The public was only informed after every family member had been informed."
However, Harry was reportedly only told about the Queen's death five minutes before the official announcement and tragically did not make it in time to say goodbye before she passed.
