The world was shocked when Prince Charles and Princess Diana announced their separation in 1992. Behind closed doors, members of the royal family like Queen Elizabeth and Princess Margaret were well aware of the couple’s troubles.

Although some members of the family were supportive of Diana amid her split from Charles, the Princess of Wales was later shunned by her in-laws after she did a revealing interview.

In 1995, Princess Diana did a tell-all interview with Martin Bashir on BBC’s Panorama. During the sit-down, Diana revealed details about Prince Charles’ affair with Camilla Parker Bowles. “There were always three of us in the marriage,” she told the television personality.

During BBC 5 Live’s 2017 podcast, “Images of Diana,” host Natasha Kaplinsky claimed the conversation ruined the Princess of Wales’ standing with the royal family. “It had a massive impact and decimated her relationship with the Palace. This was it.”

Royal biographer, Andrew Morton also claimed Queen Elizabeth and her sister Margaret were especially upset over Diana’s decision to detail Prince Charles’ affair.

“Absolutely – her next-door neighbor, Princess Margaret, who had been pretty supportive during the separation, she banned any pictures of Diana on magazines, she wouldn’t have anything to do with her,” he said.

“And that reflected a general feeling inside the Royal Family, and of course, just a few weeks afterward, the Queen, realizing that this was damaging the monarchy, this war between the Wales, and instructed that they should both divorce because things were just going to get worse.”

Prince Charles and Princess Diana finalized their divorce in 1996. Although Diana received a large divorce settlement, she was stripped of Her Royal Highness title. Royal biographer Sarah Bradford claimed Diana was devastated when she lost the prestigious title.

“She didn’t like not being HRH anymore. But she should just couldn’t help dealing a body blow, which is what she did. I think she made herself quite unpopular, a lot of people disapproved. A lot of people thought she had gone potty. The way she looked, the way she talked,” the author explained.

“It was so strange and venomous without being venomous. It just left a very peculiar impression.” 

While many members of the public sympathized with Diana, Bradford claimed the princess hurt her image. “I would say it came as a bit of a shock. That wasn’t the Diana they usually saw. It was rather sort of demonizing. The way she was made up, the way she held her head. It wasn’t sympathetic at all,” she said.

A year after Prince Charles and Princess Diana finalized their divorce, she was killed in a car crash in Paris. Charles, Queen Elizabeth, and Princess Margaret attended her funeral.
