Abstract

The central question is whether or not in multiparty systems the so‐called parties of the ‘centre’ can be defined and observed in isolation. We start from the assumption that party‐life in the centre‐space of a political system has distinctive features. Centre parties must therefore be conceptualised and analysed as phenomena sui generis and do not belong to either the left‐wing or the right‐wing of a party system. The second assumption is that every party in a parliamentary democracy is a vote seeking and policy guided actor. This means that a centre party depends on its capacity to compete with both ‘wings’ of a party system whilst occupying the centre‐space. It is then capable of becoming the ‘pivot’ of the system: its ‘centrality’ and ‘dominance’ represent ideological distinctiveness and electoral/legislative weight. The cross‐national analysis demonstrates that only a few parties are genuine pivot parties. The paper concludes with a discussion about the issue whether or not the existence of a pivot party is a blessing in disguise for the working of a democracy.
