Talking about Europe? : Explaining the Salience of the European Union in the Plenaries of National Parliaments

Abstract: National parliaments (NPs) are vital to the European Union’s (EU’s) democratic legitimacy. They are tasked with controlling their governments through oversight and scrutiny while providing a deliberative forum by offering policy alternatives, informing, and connecting citizens to the EU. NPs can only provide public accountability if they adequately meet these challenges, ensuring a well-informed citizenry that is able to form and vote according to their preferences on European integration. To do this, Members of Parliament (MPs) need to publicly communicate EU issues and important developments concerning the EU project. Yet, the use of the communicative function of NPs in EU affairs remains underexplored and questions of public accountability unanswered. Against this background, this study aims to shed light on the general salience of the EU in the plenary by adopting a principal-agent framework to analyze the factors that co-vary with the willingness of MPs to discuss the EU. Employing regression analysis on a novel dataset with observations from 17 European NPsincluding over 20,000 plenary protocols from 2006-2019, this study notes a general upwards trend of the emphasis MPs put on the EU over time, driven by critical junctures, most notably, the Lisbon treaty and the Eurozone crisis. The results of this study also indicate that MPs are most consistently responsive to elections and other key EU events. Besides, factors related to authority transfers and EU legislation as well as strategic party incentives determine how much MPs use their communicative function in the plenary. Nevertheless, this study unveils some challenges to the democratic legitimacy of the EU.
