In a twist that brings the past back to the forefront, King Charles finds himself in an uncomfortable spotlight due to the impending release of a documentary centered on recordings made by the late Princess Diana in the 1990s. The documentary, titled "Diana: The Rest of Her Story," is based on recordings Princess Diana created with biographer Andrew Morton and is slated for release next year. The content of these tapes has left King Charles apprehensive, as they shed light on some private moments and sentiments from decades ago.

One particularly poignant revelation from the recordings is Charles' initial disappointment that Prince Harry was not born a girl. The audio captures a moment where Diana recalls, "And Mommy snapped his head off and said, 'You should realize how lucky you are to have a child that's normal.'" An insider shared, "For Charles, it's yet another unseemly headache he can do without. He knows it paints him in a bad light."

The recordings, made in collaboration with Diana's close friend James Colthurst, date back to a time when Diana was still married to Charles and residing in London's Kensington Palace. Their marriage was on the rocks, and Charles had rekindled his romance with his now-wife, Queen Camilla. A source noted, "Diana wanted to get her side of the story out there at the time. She was sick and tired of being controlled by the monarchy and felt the need to speak up."

These tapes could further strain the already tenuous relationship between Prince Harry and the royal family. Following the release of his memoir, "Spare," where he was candid about his experiences and feelings towards the monarchy, these tapes might add salt to the wound. The insider remarked, "It's another kick in the gut, knowing he was ultimately a disappointment to his own father from birth. It's certainly not helping toward a long-term reconciliation. But at least at the time it was cathartic for Diana to have her uncensored say on things."

While King Charles appears open to mending fences with Prince Harry, Prince William seems more resolute in his stance. Katie Nicholl, a royal biographer, stated, "Prince William is still incredibly upset with Harry's autobiography, which, of course, really cast William in a pretty bad light." She further elaborated on the strained relationship between the brothers, referencing alleged physical altercations and tensions.

The documentary's release is sure to reignite discussions and debates about the royal family's dynamics, past and present. As the world awaits its premiere, the monarchy braces itself for the renewed scrutiny and conversations it will undoubtedly spark.
