Usually when we talk about populism in general, the most common question is "what if populism catched on in america", with figures like Huey Long. Since this is a oversaturated scenario and we got a populist in white house, what if during the populist wave of the 1930s-1960s the United Kingdom got a populist prime minister? Who would be the best candidate? A thing I want to make clear is that we are talking about democratically elected populists, like Perón or João Goulart, not a dictatorship.
