Prince Harry has accused his stepmother, Camilla, the queen consort, of leaking private conversations to the media to burnish her own reputation as he promotes a new book that lays bare the story of his life behind palace walls.

In interviews broadcast Sunday and Monday, Harry accused members of the royal family of getting “into bed with the devil” to gain favorable tabloid coverage, singling out Camilla’s efforts to rehabilitate her image with the British people after her longtime affair with his father, now King Charles III.

Harry spoke to Britain’s ITV, CBS’s “60 Minutes” and “Good Morning America″ to promote his book “Spare,” which is to be widely released Tuesday. Some U.K. bookshops plan to open at midnight to meet the demand for the highly anticipated memoir, which has generated incendiary headlines with reports that it includes details of bitter family resentments, as well as Harry and his wife Meghan’s decision to give up their royal roles and move to California.

In the interviews, Harry repeatedly blamed the media for the troubles that afflicted the couple, also known as the Duke and Duchess of Sussex, saying the coverage contributed to the rift between his brother, Prince William, and his wife, Kate.
