Today’s episode is the first in a new series of conversations with political historian David Klemperer about what causes people to switch sides, ideologies and worldviews – stories of political conversion. We begin with converts from socialism to fascism, looking in particular at the notorious case of Oswald Mosley. Why did he wind up in and then give up on the Labour Party? What made him ditch democratic politics for fascist violence? How does his political journey compare to other socialists turned fascists in continental Europe? Did he ever repent?
