Former royal butler Paul Burrell remained defiant today, despite a scathing attack by Princes William and Harry for the "cold and overt betrayal" of their late mother.
Diana, Princess of Wales, would have been mortified at his revelations this week if she were still alive, the brothers said.
But Mr Burrell refused to apologise for his new book and said he was "saddened" by the Princes' statement. He said his book, A Royal Duty, was "nothing more than a tribute" to Diana and he was "extremely proud" of it.
He also took a swipe at the Royal Family, saying no-one contacted him or said sorry following the collapse of his Old Bailey trial for theft last year. Mr Burrell, who worked closely with the Princess and claimed she called him her "rock", has released a series of extracts from the book in the Daily Mirror.
He fuelled conspiracy theories surrounding her death by writing that Diana feared for her life and that she had written of a plot to tamper with the brakes of her car.
William, speaking on behalf of 19-year-old Harry who is in Australia during his gap year, described their deep pain at the stories and appealed to Mr Burrell to end his revelations.
They would be prepared to meet the ex-royal servant to discuss the matter, Clarence House said. In a statement released yesterday, unprecedented for its strength of feeling, 21-year-old university student William said: "We cannot believe that Paul, who was entrusted with so much, could abuse his position in such a cold and overt betrayal.
"It is not only deeply painful for the two of us but also for everyone else affected 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. "We ask Paul please to bring these revelations to an end."
But in a statement issued through his publisher Penguin, Mr Burrell said: "I am saddened at the statement issued on behalf of Prince William and Prince Harry. "Saddened because I know that this book is nothing more than a tribute to their mother.
"I am convinced that when the Princes, and everyone else, reads this book in its entirety they will think differently," he said.
