Boris Johnson’s great hero is Winston Churchill. As anyone who has read his paean of praise, The Churchill Factor – How One Man Made History – published in 2014 ahead of the 50th anniversary of Churchill’s death – can testify, Johnson’s adoration is obvious.

I reviewed the book then, and wrote: “At times, it’s as if the author is writing about himself.” Johnson portrays Churchill as, “The great unifier, who appealed to ordinary people as much as he did to the upper classes, to the right and begrudgingly but appealing nonetheless, to the left.”
