This thesis examines the use of emotional language in Reform UK's senior leadership discourse on X in the year following the 2024 UK general election. The aim is to understand how emotional appeals are constructed in discourse to mobilise political support in the post-Brexit landscape. During a period of prolonged political reorientation in the United Kingdom, the emotional tone of political communication has become pivotal in establishing populist legitimacy and articulating Eurosceptic narratives. Methodologically, the thesis employs a two-step design combining systematic content analysis with qualitative discourse analysis of the most prominent emotional registers. This approach allows for both quantitative pattern recognition and qualitative interrogation of meaning-making practices. Drawing on Parrott's hierarchical model of emotions, the coding works at the primary level to distinguish six emotions: anger, fear, joy, sadness, love, and surprise. The corpus comprises 4,898 public posts authored by Reform UK's three most prominent leaders: Nigel Farage, Richard Tice, and Zia Yusuf.
