I’m by no means an expert on Hungary, never even been there, but this New Books Network interview with András Körösényi, one of the authors of The Orbán Regime: Plebiscitary Leader Democracy in the Making, was fascinating. (And also introduced me to an aspect of Weber with which I was previously unfamiliar.)
And I’m going to have to think about this a bit more, but as a concept would seem to have considerable explanatory power for the Boris Johnson regime too – as I see it close up, with institutions and (where possible) the law, being moulded to the convenience of those in charge (Brexit deal announced on December 24 and debated in one day by parliament on December 30 anyone?), and conventions in policy-making being tossed out the window (Henry VIII powers being the tool of choice).
