Ken Wharfe, Princess Diana’s former bodyguard and confidante, wrote about his ward in the book Diana: Closely Guarded Secret.
At the time the affair started, reports suggested Prince Charles was cheating on her, after which she was “ready for an affair”.
He said Mr Hewitt had “given her attention and affection”, when they met in 1986, but did not specify where.
He did, however, reveal where they used to meet up.
