In his memoir Spare, Prince Harry felt compelled to share his perspective on the events.

While there have been a number of claims that the book upset Royal Family members who were featured in it, Princess Diana's former butler Paul Burrell has also acknowledged that some of the Spare's contents offended him.

In speaking on behalf of Slingo, Burrell tells Marie Claire, "There was something more which upset me greatly."

"I was really upset, really upset [by] the fact that he referred to me as 'the butler,' 'mummy’s butler.' Well, mummy’s butler was called Paul, Harry, and you knew me, all your life you’ve known me as Paul.

"He had never known me as 'the butler' so why suddenly has there been a shift only recently, a shift to being called the butler? Suddenly I’m sort of being dismissed by this petulant prince as irrelevant because he says my tell-all book told nothing."
