Do populists practise what they preach? Intra-party democracy in populist parties

Populist parties are often described as highly centralised and personalistic, with low levels of party institutionalisation. However, there have been few empirical studies to assess the features of decision-making processes within this party family. This study aims to address this gap by examining the extent to which the internal distribution of power varies within populist parties. The Political Party Database is used to systematically compare Eastern and Western European parties in terms of intra-party democracy and the powers given to party leaders. The results suggest that although populist parties differ from non-populist parties in that they grant more power to their leaders, they are less likely to rely on plebiscitary and deliberative decision-making processes. In addition, the findings reveal that while the degree of leadership centralisation and plebiscitary decision making varies by region and ideological background, there are no differences between older and new populist parties.
