An author has claimed that Princess Diana's "secret sex diary", which contained several intimate details of the royal family, led to her alleged murder.
Author Alan Power said that he discovered the existence of the diary while researching for his book, 'The Princess Diana Conspiracy', the Daily Star reported.
The investigative writer said that Diana's dossier was powerful stuff, but it also directly endangered the monarchy's reputation.
Power alleged that the dossier contained what Charles liked in bed, women he had affairs with and what he got up to with mistress Camilla Parker-Bowles, now his wife.
He said that the X-rated diary also included bits about a senior royal and a male servant, who were caught in bed together.
Power has also alleged that "someone was keeping" the dossier and was getting ready to publish it.
