Prince Harry and Meghan Markle could return to writing about their lives in the Royal Family should their latest financial ventures fail, a royal commentator has claimed.

The Duke and Duchess of Sussex have been working on developing their contract with Netflix with a new cooking show and documentary about polo, with Meghan also set to launch her new lifestyle brand – American Riviera Orchard.

But commentator Richard Fitzwilliams noted some signs suggest their projects might fail to take off, and said the couple could opt to turn back to book writing to up their income.

Speaking to Kinsey Schofield's To Di For Daily, he said: "If Harry and Meghan don't get A-lister support, top polo players and so on and so forth, they could always be tempted to...well, there were reports originally they considering up to four books.

"One of them could be Meghan's memoir, one of them could be the 400 pages Harry said were cut from Spare because he thought they would cause problems. Another one could be his memoir when a child and so forth. So you could get more trouble in the future."
