A former royal protection officer has launched a scathing attack on Prince Harry, urging him to “engage your brain before opening your mouth” and abandon what he described as conspiracy theories surrounding Princess Diana’s death.

The sharp criticism follows reports that Harry and Meghan are working on a Netflix documentary about Diana, set for release in 2027 to coincide with the 30th anniversary of her tragic passing.

Dai Davies Condemns Conspiracy Claims

Dai Davies, speaking on GB News, expressed outrage over the Duke of Sussex’s continued remarks about the 1997 Paris car crash that killed his mother.

“One of the lectures I give when I’m lucky enough to go on a cruise ship is about Diana—what really happened in Paris?” Davies said. “And again, he regurgitates the nonsense that this summer was a conspiracy. He comes out with verbal diarrhoea on occasion, and it makes me very angry.”

Davies added, “He makes me angry because he has his truth, which I have no doubt he believes, or has been told to believe. And then we have the real truth. As an ex-cop, I pursue the real truth and evidence it, hopefully, before I open my mouth.

There’s a lovely saying: engage your brain before opening your mouth. Unfortunately, Harry has a habit of not engaging that brain, if indeed he has one.”
