Abstract Populism has been examined in depth in the last decades both from theoretical and empirical approaches. Among the topics that scholars have studied, the ideological flexibility of populist discourses is one of the most controversial and difficult to analyse. Although a large body of research has explored this peculiar characteristic of populist political discourses, this paper provides an original interpretation of populism by assessing this flexibility drawing on the importance of George Sorel’s theory in discourse theory, which could contribute to a better understanding of populist theory. Understanding populism from a discursive framework could explain the intrinsic contingency of populism and the emergence of both radical right and radical left populisms. This study aims to trace the theoretical path from the influence of Sorel’s Theory of Myth on populist discourse theory to its current implications for populist discourses, resulting in the multifaceted nature of populism.
