More about Princess Diana's imploding marriage to Prince Charles revealed as recordings are leaked

Author Andrew Morton caused a sensation in 1992 when he released Diana: Her True Story, a biography of the Princess of Wales.

The book told a side of her story that very few knew and was met with a lot of skepticism as many claimed it was all made up. Diana: Her True Story was later proven to be true.

After more than two decades, Mortan has decided to stir up that sensation again as he republishes his book along with transcripts of the tapes, which he has revealed to the Daily Mail.

The new transcripts reveal more about Diana's imploding marriage to Prince Charles. About how he played a part in her bulimia started before marriage and how devastating it was for her to find out about her husband's affair with Duchess Camilla.

"The bulimia started the week after we got engaged," Diana said in the recordings, adding, "My husband put his hand on my waistline and said: ‘Oh, a bit chubby here, aren’t we?’ and that triggered off something in me."

She revealed that she lost almost six inches from the first time she tried on her wedding dress to the wedding day itself.

About Charles' relationship with Camilla, the princess said she was already suspicious.

"I was desperate, desperate."

She said: "We always had discussions about Camilla, though... I once heard him on the telephone in his bath on his hand-held set, saying: ‘Whatever happens, I will always love you.’I told him afterwards that I had listened at the door, and we had a filthy row."

There had been points before her marriage where she realised she didn't want to marry the Prince, but went ahead anyway, leading to a depressing ten years, during which very few knew her side.

Diana met with author Andrew Morton to tell her side of the story. About the experience she said, "An author who has done me a particular favour is now writing a book on me as Diana, rather than POW [Princess of Wales]... It is a chance for my own self to surface a little rather than be lost in the system. I rather see it as a lifebelt against being drowned and it is terribly important to me."
