Butler: Not Sorry for Princess Di Revelations

Oct. 24 -- — As Princess Diana's former butler gives the media inside information about his time with her — claiming she never wanted to divorce Prince Charles, and that she feared for her safety — her sons say they feel betrayed.

"We cannot believe that Paul who was entrusted with so much could abuse his position in such a cold and overt betrayal," Prince William and Prince Harry said in a joint written statement.

"It is not only deeply painful for the two of us but also for everyone else affected," the statement continued, "and it would mortify our mother if she were alive today and, if we might say so, we feel we are more able to speak for our mother than Paul."

In a statement given to ABCNEWS and later read to the British media, Burrell said he is "saddened" by the princes' reaction to published details from his forthcoming book, A Royal Duty, which "is nothing more than a tribute to their mother." He said he hopes William and Harry will "think differently" upon reading the entire book.

"My only intention in writing this book was to defend the princess and stand in her corner," Burrell said.

However, he added, he would not apologize for the book.

"I would also like to point out that following the collapse of my Old Bailey trial last year, no one from the royal family contacted me or said 'sorry' for the ordeal myself, my wife and my sons were put through," Burrell said. "Neither do I say 'sorry' for writing this book of which I am extremely proud. And I am convinced the princess would be proud of it too. I've told the truth. The British public should know the truth."

Diana Never Wanted Divorce

In his exclusive interview with Barbara Walters for ABCNEWS' 20/20, Diana's former butler and confidant says the princess never wanted to divorce Prince Charles, and hoped for a reconciliation with the prince in spite of Charles' highly publicized relationship with Camilla Parker Bowles.
