Prince Harry, Meghan Markle declined queen’s invite to Balmoral twice, author claims: 'A source of regret’

Vanity Fair's royal correspondent Katie Nicholl has written a book titled "The New Royals." In it, she details the Duke and Duchess of Sussex's frustrations with royal life.

"The queen traditionally hosted a big gathering for her grandchildren and great-grandchildren," Nicholl told Fox News Digital. "It was always a weekend that she looked forward to. And on this occasion, the Sussexes didn’t go. I was told that it wouldn’t have fit their narrative at that point. The narrative was very much ‘this is us against them.’ There was that sense of separation. And perhaps turning up and playing happy families wouldn’t have fit into that narrative."

In her book, Nicholl alleged that the Sussexes chose to take their son Archie to Ibiza and the South of France, a decision that "raised eyebrows." At the time, reports alleged that the getaway coincided with Markle’s birthday on August 4.
