Does European Integration Lead to a `Presidentialization' of Executive Politics?

In this article, we address recent claims that executive— legislative relations in parliamentary democracies are undergoing important changes owing to either a `presidentialization' or a `Europeanization' of domestic political systems. Therefore, we test empirically whether parliamentary democracies are indeed experiencing changes in executive—legislative relations and whether these developments can, in part, be explained by an increase in European integration. Using data on ministerial selection in Swedish cabinets during the years 1952—2006, we find that there appears to be a slight tendency towards `presidentialization', which is indicated by a decrease in ministers with a parliamentary background being appointed, and that there exists some support for the notion that Sweden's political and economic integration into the European Union is part of the explanation for this change.
