While some Eurosceptic members of the European Parliament (MEPs) engage constructively with legislative work, others opt for blanket opposition. This is reflective of distinct legislative roles of MEPs and results in differences in the representation of Eurosceptic voters. We ask whether and under what conditions Eurosceptics’ behaviour within the European Parliament is shaped by the potential for public attention. Combining novel data on voting behaviour in committee-level as well as in plenary-level roll calls, we leverage the difference in public attention that the two arenas attract. Our analysis draws on variation in attendance and voting behaviour patterns across levels to test competing explanations of how and to what extent Eurosceptic legislators contest European integration when in the “public eye” in plenary as opposed to more secluded everyday work in committees. The findings demonstrate that MEPs are mindful of the distinct principals and audiences to whom they pander. The paper maps the behaviour and contributes to a growing literature on legislative behaviour of Eurosceptics.
