What can explain the strong euroscepticism of radical parties of both the right and the left? This article argues that the answer lies in the paradoxical role of nationalism as a central element in both party families, motivating opposition towards European integration. Conventionally, the link between nationalism and euroscepticism is understood solely as a prerogative of radical right‐wing parties, whereas radical left‐wing euroscepticism is associated with opposition to the neoliberal character of the European Union. This article contests this view. It argues that nationalism cuts across party lines and constitutes the common denominator of both radical right‐wing and radical left‐wing euroscepticism. It adopts a mixed‐methods approach, combining intensive case study analysis with quantitative analysis of party manifestos. First, it traces the link between nationalism and euroscepticism in Greece and France in order to demonstrate the internal validity of the argument. It then undertakes a cross‐country statistical estimation to assess the external validity of the argument and its generalisability across Europe.

This article examines the relationship between nationalism and liberal values and, more specifically, the redefinition of boundaries between national communities and others in the rhetoric of radical right parties in Europe. The aim is to examine the tension between radical right party discourse and the increasing need to shape this discourse in liberal terms. We argue that the radical right parties that successfully operate within the democratic system tend to be those best able to tailor their discourse to the liberal and civic characteristics of national identity so as to present themselves and their ideologies as the true authentic defenders of the nation's unique reputation for democracy, diversity and tolerance. Comparing the success of a number of European radical right parties ranging from the most electorally successful Swiss People's Party, the Dutch Pim Fortuyn List and Party for Freedom to the more mixed French Front National, British National Party and National Democratic Party of Germany we show that the parties that effectively deploy the symbolic resources of national identity through a predominantly voluntaristic prism tend to be the ones that fare better within their respective political systems. In doing so, we challenge the conventional view in the study of nationalism that expects civic values to shield countries from radicalism and extremism.

Within the broader debate on the Greek crisis, the theory of 'populist democracy' postulates that populism is fundamental to the sustenance of the Greek political system and is at the heart of Greece's endemic domestic weaknesses. This article tests this assumption empirically through the use of a sophisticated framing analysis of speeches delivered by the leaders of the five parties in the Greek parliament in the period 2009-11. The findings confirm that populism: (a) is expressed through the narratives of political actors; (b) is observed across the party system; (c) is expressed in the forms of blame-shifting and exclusivity; and (d) differs depending on position in the party system. The article contributes to the debate by testing and building on the theory of democratic populism, providing a novel way of measuring and operationalizing populism and identifying a new typology that distinguishes between mainstream and fringe populism.* We thank Claudio Radaelli, the LSE Hellenic Observatory and the three anonymous reviewers of the Journal of Common Market Studies.

The purpose of the Exchange feature is to publish discussions that engage, advance and initiate new debates in the study of nations and nationalism. This Exchange article is on the subject of ‘Populism and Nationalism’. Each contributor addresses the following four questions on the subject: (1) What is populism and what role does it play within the context of democratic politics? (2) Does populism cut across left–right lines? (3) What is the relationship between nationalism and populism? (4) Are contemporary populist movements across Europe and the West comparable? Our aim is to generate a thought‐provoking conversation with regard to the rise of populism in Europe and the West.

Does the economy affect patterns of far-right party support across countries? This article reconceptualizes micro-level analyses that focus on the effect of unemployment through a framework of costs, risks and the mediating role of labour market institutions. It then derives several hypotheses and tests them on the results of the previous three EP elections in all EU Member States. Findings from multiple regression analyses indicate that unemployment, real GDP growth, debt and deficits have no statistically significant effect on far-right party support at the national level. By contrast, labour market institutions influence costs and risks: where unemployment benefits and dismissal regulations are high, unemployment has no effect, but where either one of them is low, unemployment leads to higher far-right party support. This explains why unemployment has not led to far-right party support in some European countries that experienced the severity of the 2008 eurozone crisis.
