Princess Diana eclipsed Prince Charles while they were married to each other. But even after their divorce, the mom of two made sure that she would continue to overshadow her ex-husband.

In the book “The Firm,” royal author Penny Junor said that the royal couple’s acrimonious split wasn’t the end of the war between them. Prince Charles and Princess Diana’s divorce was simply the end of their 15-year marriage.

“Diana was no happier outside the family she seemed to have hated so much than she was within it. She was still angry with Charles and determined to embarrass and upstage him at every opportunity… And, according to the opinion polls, she took the majority of the country with her,” Junor said.

During his difficult time, Prince Charles released a statement saying that he had no plans to get married again. But his statement was proven to be false years later. Prince Charles wed Camilla Parker Bowles in a civil ceremony in 2005. And at that time, the Duchess of Cornwall was still disliked by Princess Diana’s avid supporters.

Following Prince Charles’ announcement that he has no plans to get married again, a debate about the monarchy was televised. Approximately 3,000 live audiences were selected to watch the show live. And every time Camilla’s name was mentioned, they would boo and hiss loudly.

At that time, the public wasn’t ready to forgive Camilla and Princess Diana was far from forgiving her ex-husband’s mistress.

Meanwhile, even though Prince Charles and Princess Diana mutually decided to divorce each other, the couple still couldn’t hide their sadness over the matter. In the Channel 5 documentary “The Royal Family at War,” royal expert Ingrid Seward said that Prince Charles and Princess Diana both cried on the sofa after their divorce was finalized.

By the looks of it, the former couple was sadder over their split because it meant that their sons wouldn’t grow up with both parents around.
