Prince Harry and Meghan Markle may think they did the right thing by airing their troubles in a recent documentary and taking on the press with a lawsuit, but one royal expert is warning the pair that their actions are echoing ones Princess Diana made in the 90s, and could be destructive when it comes to the pair’s future.

In an interview with Daily Star Online, royal expert Richard Fitzwilliams revealed that doing the interviews they did in the documentary “Harry and Meghan: An African Journey,” as well as other public comments railing against the media coverage against them were actually very destructive overall, and they should have been advised against doing so because of how similarly they reflect bad publicity from the past.

“It was highly unwise to give interviews of this sort which, whatever their appeal to Millennials, has led to ‘concern’ being expressed for Harry and Meghan appearing ‘fragile’ by sources close to William and has led to a source close to the Sussexes talking about Harry and Meghan ‘singlehandedly modernizing the royal family,’” he said. “This is deeply destructive and has echoes of the 1990s.”

The comment references Princess Diana’s behavior during that decade, which was characterized greatly by not only the breakdown of her marriage but later on, her death. When she opted to open up about her marriage troubles in a bombshell interview that saw her famously declare that there had been “three people” in her marriage.

Naturally, the royal couple isn’t likely trying to repeat history, as that was one of the concerns mentioned in their official statement about the lawsuit they had filed against Associated Newspapers for publishing a private letter Markle wrote to her father in the Mail on Sunday.

“Though this action may not be the safe one, it is the right one. Because my deepest fear is history repeating itself,” Prince Harry said at the time. “I’ve seen what happens when someone I love is commoditised to the point that they are no longer treated or seen as a real person. I lost my mother and now I watch my wife falling victim to the same powerful forces.”
