The late Queen Elizabeth is protecting her right-hand woman from "beyond the grave" after handing her a trump card, a source has claimed.
As Her Majesty's dresser and confidante, Angela Kelly published two books about her role in the palace after the monarch granted her permission to do so.
It was understood that she was given the late monarch's blessing to crack on with a third book, but recent reports have suggested that King Charles put an end to that plan after getting Ms Kelly to sign a NDA (non-disclosure agreement) in exchange for a new home in Yorkshire.
