Mirko Draca of CAGE at the University of Warwick discusses the political polarisation that has emerged over the past few years over issues such as climate change and immigration. Survey data reveal the existence of left-wing and right-wing anarchist types from the late-1980s onwards, but both types appear to have been activated over the last five years or so. Draca was speaking to VoxEU at the RES 2019 Conference.
