Prince William ‘blindsided’ by Harry, Meghan return as Kate fears new turmoil from royal feud: experts

Prince William was reportedly "blindsided" by Prince Harry and Meghan Markle’s surprise decision to return to the U.K. with their children.

Several royal experts told Fox News Digital that the Prince and Princess of Wales are "concerned" about the Duke and Duchess of Sussex returning for an extended period beginning this month.

Prince Archie and Princess Lilibet are set to begin school there in September, People magazine reported.

"Prince William was blindsided," Kinsey Schofield, host of YouTube’s "Kinsey Schofield Unfiltered," told Fox News Digital.

PRINCE HARRY, MEGHAN MARKLE’S UK MOVE PUTS FRESH SPOTLIGHT ON THEIR EXPLOSIVE CLAIMS AGAINST ROYAL FAMILY "He had found Harry’s recent eagerness to publicly signal that he wanted to spend more time in Britain unusual, but that is very different from anticipating a full return.

William now has to navigate a situation he did not create, did not ask for and, given the state of their relationship, almost certainly would not have chosen." Fox News Digital reached out to Kensington Palace for comment.

In a statement shared with The New York Times, a spokesperson for the Sussexes said, "On the heels of a wonderful trip with family and friends this summer, Harry and Meghan have decided to spend an extended period in the U.K. this autumn.

They are excited to have their children spend more time in the country that’s such an important part of their family’s story." The spokesperson confirmed that the couple’s businesses will remain unchanged and based in the U.S.

Meghan and Harry will also keep their home in California.

British broadcaster and photographer Helena Chard told Fox News Digital that the Waleses are "feeling uneasy" about facing another chapter in the "endless Sussex soap opera." WATCH: PRINCE WILLIAM UNLIKELY TO RECONCILE WITH PRINCE HARRY SOON: EXPERT "It’s about broken trust," Chard explained.

" Prince William is said to feel that Harry and Meghan have spent years attacking the institution, then monetizing their grievances through a very lucrative media operation.

From his view, it’s an ongoing campaign for maximum impact and self-gain.

He’s not going to fuel it, and he’s not going to endorse behavior he sees as damaging." William and Kate were seen arriving in Scotland on Thursday, where they’ll spend time with King Charles at Balmoral Castle.

The royal family has spent summers at the Scottish estate since the reign of Queen Victoria, with family members traditionally hunting, fishing and horseback riding there.
