Burrell received much criticism for copying Diana's letters and his integrity was called into question. He referred to himself as the princess's "rock," and the coroner, Lord Justice Scott Baker accused him of being "a rather porous rock - given in mind what leaked out."
Burrell has since continued to profit from his closeness to the princess.
In 2003, Burrell released his autobiographical book, A Royal Duty, which follows his career as a member of the Royal Family's staff. It deals in detail with his time as butler to the Prince and Princess of Wales at Highgrove House in Gloucestershire, his move to Diana's staff at Kensington Palace after her divorce from Prince Charles, and his acquittal on serious theft charges against him. The book was an international bestseller, and was updated in a paperback edition in 2004.
Also in 2004, he was runner up in the ITV reality TV show, I'm a Celebrity... Get Me Out of Here!. He also had arguments related to his discussions with journalist Janet Street-Porter, regarding criticism to his predilection for talking about the British Royal Family.
