Thinking locally,acting supranationally: Niche party behaviour in the European Parliament

Recent research on the European Parliament (EP) has neglected the idiosyncrasies of niche parties. Similarly, analyses of niche parties have not fully engaged the literature on the EP. This article builds on both literatures by analysing niche party behaviour in the EP as a distinct phenomenon. It is argued that niche parties will respond differently to institutional stimuli than parties more generally. To test this argument, Hix, Noury and Roland's work on EP party voting behaviour is replicated concentrating on niche parties only. It is found that participation in national government and institutional changes affect niche party legislators' voting behaviour, whereas they do not for legislators in the EP overall. These results have important implications for understanding both party behaviour in the EP and niche party behaviour more generally.
