The Duke of Sussex is reportedly contacting his ex-girlfriends to share their memories in his book.
Journalist Robert Crampton branded the move a “high-risk strategy”.
Writing in The Times, he added: “His mates, plus old flames Chelsy Davy and Cressida Bonas, have been souls of discretion thus far.
“But once they start talking, they might get a taste for it, especially when and if one of them falls on hard times. Scandal has a habit of emerging eventually into the light.”
Prince Harry’s former flames include on-off girlfriends Chelsy Davy and Cressida Bonas.
