Bob Woodward’s second book on the Trump White House has a title, Rage, and promises to reveal the secrets of “25 personal letters exchanged between [Donald] Trump and North Korean leader Kim Jong-un that have not been public before”.

In the letters, according to details from Simon & Schuster published on the book’s Amazon page on Wednesday night, “Kim describes the bond between the two leaders as out of a ‘fantasy film’, as the two leaders engage in an extraordinary diplomatic minuet”.

Rage, the sequel to Fear, is due out on 15 September, its cover showing Trump’s face in extreme close-up.
