The short-lived hope for contagion: Brexit in social media communication of the populist right

Brexit was perceived as a Pandora’s box moment by both Eurosceptic and pro-integration parties in the EU, as they expected it would embolden Euroscepticism by providing a paradigm to be followed. This article explores the initial reactions of nine Populist Radical Right parties to Brexit and how they evolved in tandem with the unfolding of negotiations. It also discusses possible reasons for the differentiation in the responses of those parties, from triumphant to moderated reactions. The empirical basis is a dataset that contains the public communications of these parties on Twitter between 2015 and 2020. The results show that although there was initial differentiation with some parties calling for referenda in their own countries, by 2017 every party’s communication on Brexit drastically decreased, and by the time the UK left the EU (January 2020), calls for secession had disappeared from their discourses.
