The recent upsurge of electoral success from the Brexit Leave campaign and Donald Trump’s presidential campaign 2016, confirm that populist politics has taken a greater role in Europe and in the U.S. The purpose of this research is to see to what extent each of the two campaigns are populist, and whether their statements are similar to each other. This will increase further knowledge about the populist phenomenon and its complexity. Hence, comparative analyses of six speeches from Brexit’s Leave campaign and Trump’s presidential campaign have been conducted through the framework of Mudde’s minimal definition of populism. The results show that both campaigns have populist features and that they have some commonalities, but still vary in the details, due to the countries’ historical, social and economic backgrounds. The two campaigns’ representatives are using similar populist strategies in order to reach their audiences. It is further recommended to expand this research and examine Trump’s presidency and its impacts with the UK’s process of leaving and its outcomes, which will provide a further understanding of the populist upsurge as well as its consequences.
