• Queen Elizabeth and Prince Philip were "shocked" and "irritated" by Harry's decision to quit, a royal expert says
  • Ingrid Seward says Prince Philip found the split difficult because he is very fond of his grandson
  • The Queen wanted the Sussexes to be the "new face of royalty," the author says

Queen Elizabeth II and Prince Philip may still be unable to understand what caused their grandson, Prince Harry, to give up his privileges and step down as a senior member of the British royal family earlier this year, according to an expert.

Royal biographer Ingrid Seward, who recently released “Prince Philip Revealed,” said she believes that the Queen and her husband are still sad and upset with the Duke of Sussex's decision to quit the royal family and move to the U.S. with Meghan Markle and their son, Archie.

"I think it was a huge shock and then as very often happens shock then turns to irritation because you think why? What have we all done wrong and what it is that they want and what is it that they haven’t got?" the editor-in-chief of Majesty magazine told Page Six.

"They’ve got a beautiful house, they’ve got a beautiful child, they were doing what they wanted to do, their voices were being heard and I think they just couldn’t understand and probably still don’t," she continued.

Seward also speculated that "Megxit" came as a huge shock to Queen Elizabeth and Prince Philip because the Sussexes were supposed to be the "new face of royalty." Prince Harry and Markle were expected to help bring the monarchy into the 21st century together with Prince William and Kate Middleton.

"And I think they could hardly believe it when Harry announced they were leaving for North America and wanted out of royal life," the expert said.

The royal author went on to speculate that Prince Harry's decision to turn his back on his royal duties may have been difficult for his 99-year-old grandfather to accept as he has always been very fond of the Duke of Sussex.

"Harry is spontaneous, he’s fun and he’s a bit of a daredevil or he was and Philip, when he was young, was all these things too, So I think he saw a little bit of himself in Harry and the two of them were able to communicate very well," Seward said of Prince Philip.

Seward also commented on Prince Harry and Markle's 2018 royal wedding, describing it as "magical" but "very flamboyant." She noted that the former actress may not have understood just how understated the British are.

Denying claims that she was anti-Meghan, Seward said she thinks Markle "has a big heart" and that she and her husband only "want to make things better." But instead of achieving this, the royal expert believes they only "made things worse."

Prince Harry and Markle have now settled down in their family home in Santa Barbara, California, and are gearing up to debut their new charitable venture, launching the website for their Archewell Foundation in October.
