Princess Diana had publicly executed Prince Charles in her interview with BBC.

According to Penny Junor in her 2017 biography “The Duchess: The Untold Story,” Princess Diana’s infamous Panorama interview was a “public execution” for the Prince of Wales. In the interview, the Princess of Wales told Martin Basher that “there were three of us in this marriage, so it was a bit crowded.”

Princess Diana was implying about Prince Charles and Camilla Parker Bowles’ affair. Due to her shocking revelation, she gained the sympathy of the public.

“It was a superb performance worthy of an Oscar and was shrouded in such secrecy that not even the governors of the BBC had an inkling,” Junor wrote.

Prince Charles didn’t watch the interview but was immediately told about it when it aired. Meanwhile, the Duchess of Cornwall watched it at home with her family and “laughed at the sheer theatricality of it.”

“She had manipulated Bashir, just as she had (biographer) Andrew Morton, turning her private battle with the prince into a public execution without a thought for her children,” Junor continued.

Princess Diana reportedly told her private secretary about the interview but refused to share the details. However, she told him that “it’s terribly moving.”

Many comforted Princess Diana that everything will be alright. However, Junor said that she had it wrong because Queen Elizabeth II “lost her patience” and ordered the Prince and Princess of Wales to divorce, instead.

Princess Diana’s controversial interview shocked the palace. Princess Margaret found her statement “unacceptable.” Her interview only worsened their rivalry and escalated it to a cold war. Princess Margaret reportedly told her staff to never talk to anybody from Princess Diana’s apartment.

Meanwhile, Queen Mother detested her biography with Andrew Morton. Queen Elizabeth II’s mom couldn’t understand why Prince William and Prince Harry’s mom had to open up about her rocky marriage to a biographer.

Queen Mother told William Shawcross that it’s always a mistake to talk about one’s marriage. Also, Princess Diana’s public rejection of her husband was contrary to what Queen Mother believed and practiced whose life was based on obligation, discretion, and restraint.
