At the conceptual level, populism and Euroskepticism are both closely related and inherently distinct. Notably, populism is a general set of ideas about the functioning of democracy, while Euroskepticism concerns a position toward a more concrete political issue (European integration). When focusing on the political supply side (political parties) as well as the demand side (citizens), populism and Euroskepticism can often be observed in tandem. In practice, many populist parties are Euroskeptic, and many Euroskeptic parties are populist. Euroskepticism and populism can typically be found at the ideological fringes of party systems, in particular among parties with radical left socioeconomic positions on the one hand and radical right sociocultural positions on the other. While little is known about the relationship between populist and Euroskeptic attitudes among citizens, it is clear that such attitudes contribute to support for populist and Euroskeptic parties. Moreover, preliminary analyses indicate that at the level of voters, populist and Euroskeptic attitudes often coincide. Future studies (considering both the supply and the demand sides) should focus in greater depth on how the two concepts are related and how they interact in practice.
