Which virtues, and why these, are most important for politicians? While philosophical discussions on virtues in politics are extensive, empirical investigations into the virtues politicians themselves value remain limited. This article addresses this gap through in-depth interviews with 74 Swedish parliamentarians. Analyzing these interviews using a structured multi-level coding approach, I make three main claims. First, the cardinal virtue in the Swedish parliament is the ability to separate ideas from those who hold them; this principle is seen as vital for fostering political trust within parliament and with the public. Second, virtue pluralism is essential within parliamentary and party groups as the virtues politicians prioritize depend on the broader virtue composition of their group. Third, virtues can be categorized into five key themes—entrepreneurial, social, integrity, wisdom, and craftsman—reflecting the multifaceted nature of parliamentary representative roles and responsibilities. Collectively, these findings underscore the interdependent nature of virtues in political practice, where the value of specific virtues is shaped by group dynamics and the presence or absence of the cardinal virtue. This study provides novel empirical insights into how national political leaders perceive and value virtues in politics, contributing to the literature on political ethics, representation, and leadership.
