This article aims to provide a comparative analysis of Law and Justice’s participation in the European Parliament elections from 2004 to 2024. The research utilized campaign materials, party leaders’ statements, election results, statistical data, and academic and journalistic studies. The analysis draws on the concept of populism understood as discourse and political rhetoric. This article assumes that Law and Justice is the largest populist party in the Polish political scene. The research found that Law and Justice gained support and seats from election to election, taking first place in 2019. Research has confirmed that in election campaigns leading up to the European elections, attention focused primarily on domestic issues, but European issues, primarily concerning the EU model and regulations and their impact on Polish national interests and the security of Poland and Poles, increasingly took center stage. The plebiscitary nature of the 2019 and 2024 European elections was confirmed.
