• The royal family hopes Princes Harry and William can get through Prince Philip's funeral "without stress or animosity," a report says
  • They reportedly also hope the brothers will take the time to "bond" and work on their issues
  • It is expected that the two will be "cordial" during the service for the sake of their grandmother, Queen Elizabeth

The royal family hopes that Prince Harry and Prince William will take time to sort out any issues they may have before Prince Philip's funeral on Saturday, according to a report.

After arriving in the U.K. Sunday, Prince Harry reunited with his first cousin, Princess Eugenie, who is staying at his Frogmore Cottage home. However, it is unclear whether or not he has met with his father Prince Charles or brother Prince William after returning to his home country for the first time since stepping back as a working royal last year.

The royal siblings are rumored to be at odds, especially after the Duke and Duchess of Sussex's March interview with Oprah Winfrey. However, the rest of the royal family are hoping that they will bond and ease the tension ahead of their grandfather's funeral, Us Weekly reported.

"The rest of the family are just hoping the brothers can grit their teeth and get through this without stress or animosity," an unnamed source told the outlet. "There’s also a hope that they can bond in person and put the past behind them, though it’ll be difficult due to the resentment and anger that’s existed on both sides."

The insider noted that it may not be easy for Prince William and Prince Harry to fully set aside their tenuous relationship. However, the source said it is likely they will both take the high road for their grandmother Queen Elizabeth's sake.

"The likelihood is that they’ll get through this quietly and be cordial yet somewhat detached. They certainly won’t want to stress out their grandmother with any ill will or negativity, so that’s one positive," the insider added.

Royal expert Andrew Morton has a similar opinion, saying that Prince Charles and Princess Diana's sons likely won't air their dirty laundry in public, especially when they are mourning their grandfather.

"I think that they’ll behave very well and … there will be a degree of interaction," he told Us Weekly. "They will be cordial, as opposed to friendly [but] I don’t think there’ll be anybody putting their arms around one another."

Prince Harry will not be staying long in the U.K. and will leave shortly after Prince Philip's funeral, Page Six earlier reported. According to the report, the Duke of Sussex wants to return to California as soon as he can and be reunited with his wife, Meghan Markle, and their son, Archie. He reportedly already misses his family and was worried about leaving Markle behind as she's far along in her pregnancy.
