As you wish? Public preferences for models of representation and MPs’ role orientations

How much autonomy elected representatives should have in looking after the interests of their constituents is a central question of democratic theory. While much research has been conducted on the representational roles adopted by elected representatives, we currently lack an understanding of citizens’ preferences for contrasting models of representation, more specifically whether they believe representatives should primarily act as instructed delegates, closely following public opinion or rather as trustees, relying on their own convictions and judgement. As a result, we know relatively little about how congruent citizens’ and politicians’ representational preferences are, whether some subgroups of citizens and politicians are more congruent with each other than others and whether citizens’ and politicians’ representational preferences are driven by the same determinants. Using data from 13 countries, we assess the level of congruence between voters’ and MPs’ preferences in representational style. In all countries, citizens favouring delegate-style MPs are poorly represented as the vast majority of representatives display a moderate to strong preference for trusteeship. Analysing subgroups of politicians and citizens according to party family, ideology, inclusion in government, populism and social class reveals that MPs from left-wing or right-wing radical and populist parties, representatives sitting on the opposition benches and those belonging to lower classes tend to hold representational preferences that are more in line with the preferences of their own supporters or individuals belonging to the same group as themselves, but also with those of the entire electorate. However, even among these politicians there are few delegates. Examining whether citizens’ and politicians’ representational preferences are driven by similar determinants, we assessed the influence of their ideological orientations, socioeconomic status and support for (or affiliation with) a party in government on their representational preferences. For citizens, our results indicate that locating oneself on the right of the ideological spectrum is related to higher scores on the delegate–trustee scale, while supporting a populist party seems to decrease voters’ favourability toward trusteeship. Politicians’ preferences could not be explained by similar factors as none of the tested factors were significant. In line with our congruence analysis, there seems to be little variation in MPs’ representational preferences. Even groups of MPs that can be thought of as most likely to be delegates turn out to be staunch trustees, potentially causing frustration among citizens preferring delegate-style representation.
