Paul Burrell reveals about James Hewitt

Burrell dismissed the rumours that Diana's lover James Hewitt is Prince Harry's father. He said that all these speculations were made up. "It's something that's been made up. It was just because Harry had red hair, but all the Spencers have red hair. If it ever did come up, Diana just laughed because it is farcical," he told The Mirror.

"Now, for Harry's sake, everyone should put it to rest. He must be sick of it."

Diana's letter to Paul Burrell 

In his book, A Royal Duty, Burrell also published a handwritten letter by Diana to him in October 1996. In her letter, she claimed, "This particular phase in my life is the most dangerous - my husband is planning 'an accident' in my car, brake failure and serious head injury in order to make the path clear for him to marry Tiggy. Camilla is nothing but a decoy, so we are all being used by the man in every sense of the word."
