Fox News reports, Prince Philip is “very, very disappointed” in Meghan Markle’s failure to “support the monarchy.”

Ingrid Seward, a Royal biographer, said the Duke of Edinburgh, 99, gave up his naval career to support Queen Elizabeth II when she took the throne in ’52.

Seward, has been covering the royal family since the 80’s and has written more than 20 books on the royals.

On October 20 Seward will be releasing a new book called “Prince Philip Revealed.”

Seward said, “I think he’s very, very disappointed because I think he feels he gave up his naval career in order to stand by the Queen and help the monarchy. And why can’t Meghan just give up her acting career, support her husband and support the monarchy? As he used to say to [Princess] Diana, this is not a popularity contest, this is all of us working together.”

“He just cannot understand why she couldn’t support Harry and help him rather than wanting to have her voice.”

“Of course it irritates him hugely. And when they had the Sandringham summit, Prince Philip was seen leaving the house very swiftly before they all arrived. He simply doesn’t want to get involved anymore.”

“He has struggled greatly, for example, with what he sees as his grandson Harry’s dereliction of duty, giving up his homeland and everything he cared about for a life of a self-centered celebrity in North America,” Seward elaborated.

“He has found it hard to understand exactly what it was that made his grandson’s life so unbearable. As far as Philip was concerned, Harry and Meghan had everything going for them: a beautiful home, a healthy son, and a unique opportunity to make a global impact with their charity work.”

“For a man whose entire existence has been based on a dedication to doing the right thing, it appeared that his grandson had abdicated his responsibilities for the sake of his marriage to an American divorcee in much the same way as Edward VIII gave up his crown to marry Wallis Simpson in 1937,” she continued.

A spokesperson said, “The Duke and Duchess of Sussex moved into their family home in July of this year. They have settled into the quiet privacy of their community since their arrival and hope that this will be respected for their neighbors, as well as them as a family.”

Seward alleged that after the Duke and Duchess of Sussex made their intentions clear, Philip no longer wanted to get involved.

The Sussexes have recently settled down in Santa Barbara, Calif., after living in Los Angeles and Vancouver, Canada.

A representative for the couple confirmed to Fox News that they purchased a home in the coastal city.

A source told Page Six, who first reported the news, that the Duke and Duchess of Sussex hope this is where their son, Archie, 1, can grow up and lead “as normal a life as possible.”
