Britain's Prince Charles is said to be "furious" over a former aide's plans to publish a tell-all book.
Queen Elizabeth's former Press Secretary Dickie Arbiter - who worked at Buckingham Palace for 12 years, including when the prince's marriage to Princess Diana broke down and at the time of her death in 1997 - is set to spill his secrets of royal life in a forthcoming biography and his former employers are reportedly worried about what he could reveal.
A source told the Daily Mirror newspaper: "Charles is furious. This man was a trusted friend.
"He is raking over the breakdown of the marriage and the Prince has been asking aides 'Why do we have to go through this all again?'
"It is just a case of a man who he thought was a friend and who could be trusted cashing in on the misery of that time. It is disloyal.
It is believed the royals have taken legal advice in a bid to halt the publication of the book.
The source added: "Arbiter has been told that he does not have official permission to write this book and a legal team has reviewed all his old contracts in a bid to try and find a way to stop it."
Dickie, 73, has admitted to signing the Official Secrets Act and signed a confidentiality agreement while working for the queen between 1988 and 2000 but insists his book won't break any confidences.
