Sam's guest in this week’s Book Club podcast is the FT’s foreign affairs columnist Gideon Rachman. In his new book The Age of the Strongman, he takes a global look at the rise of personality-cult autocrats. He tells Sam what they have in common, what’s new about this generation of strongman leaders - and why his book places Boris Johnson in a cast including Putin, Orban, Bolsonaro and Duterte.
