Prince Philip would ‘turn in his grave’ over Harry changing kids’ surname: expert

A royal error.

Prince Harry and Meghan Markle opted to give their kids, Prince Archie, 4, and Princess Lilibet, 2, the last name of Sussex rather than Mountbatten-Windsor.

This moniker would have angered the late Prince Philip if he was still alive — according to a royal expert.

The Duke of Edinburgh died in April 2021 at the age of 99, and the surname of Mountbatten-Windsor was bestowed upon his male-line descendants since 1960.

Royal expert Ingrid Seward penned for the Daily Mail how the Greek prince would have been royally peeved — and would “turn in his grave” — at the Duke of Sussex’s choice to change his kids’ names.

She wrote that Harry’s decision “will only serve to further distance the prince and his children” from the Firm.

The House of Windsor changed their own name in 1917 from Saxe-Coburg and Gotha.

The dynasty transformed their epithet due to the anti-German sentiment rife during World War I.

When the late Queen Elizabeth became the monarch in 1952, Philip was “wounded” that his children would be Windsors instead of Mountbattens.

Before Philip married Elizabeth in 1947, he renounced his claim to the Greek and Danish thrones and took his mother’s last name, Mountbatten.

“How sad, therefore, that only three generations later, Harry should so blatantly disregard his grandfather’s wishes and effectively abandon the family name for which Philip had fought,” Seward said.

Earlier this month, Archie and Lilibet’s official name changes were announced on Harry, 39, and Meghan’s new website Sussex.com.

The couple received massive backlash for their relaunched site, which was previously called “SussexRoyal.com.”

“The office of Prince Harry & Meghan, the Duke and Duchess of Sussex,” text reads alongside Meghan’s coat of arms and the pair’s biographies.

The “Suits” alum, 42, and the Invictus Games founder’s site was also seen as a betrayal to the Queen, as they seemingly promised they would not use their titles for financial gain after they left the royal family in 2020.

The “provocative” decision to name their site after their titles will be a “big challenge” for Buckingham Palace, an insider told Daily Mail on Feb. 14.

This duplicity is being seen as breeching the agreement, “if not in letter, certainly in spirit.”

“Prince Harry and Meghan are the Duke and Duchess of Sussex. That is a fact. It is their surname and family name,” one insider added.

“Buckingham Palace may have its hands tied in taking action,” another source explained.
