The book will reveal untold stories of his life working for the Royal Family and will be published in September. This will include an insight into his friendship with Princess Diana before her death in 1997, as well as stories involving Prince William and Prince Harry, whom he watched grow up.

While the soon-to-be-published memoir is likely to stir up some unease among the royals, the ex butler has made a comment on social media that is very telling.

Under a post about his upcoming book release, a member of the public commented: "Some royals will not be thrilled."

Burrell replied to the comment with a very telling five-word statement. He wrote: "It is all very positive!"

This comment may come as a surprise for some, as Burrell's first book, A Royal Duty, published in 2003,

The book is believed to have resulted in the royals no longer trusting Burrell, who had worked for Queen Elizabeth II, the now King Charles, and the late Princess Diana.

In 2003, Clarence House also issued a statement from Diana's sons, and after snippets of the memoir were made public.

In the statement, they pleaded for the butler not to publish the book.

, it read: "We cannot believe that Paul, who was entrusted with so much, could abuse his position in such a cold and overt betrayal. It was 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."

The book still went on to be published.
