Party Change and Europeanisation: Elements of an Integrated Approach

The literature on party organisational change emphasises environmental factors as well as internal circumstances. The literature on Europeanisation and political parties privileges the EU as a key environmental factor in terms of change. This article combines insights from the party organisation and Europeanisation literatures in order to more precisely conceptualise the EU as a stimulus and therefore causal factor in party organisational change. Two types of party change are analysed, new party positions (MEPs and specialised EU party staff) and party leaderships' responses to internal dissent over the EU. Linking a specific form of EU stimulus to a particular party goal helps to explain certain types of change, while inter-governmental bargaining may produce uncertainty for domestic political actors thereby inducing defensive reactions.
