In this paper, I analyze the construction of the trope of irony in a political interview, more specifically the interview with a Spanish politician on television in 2013. Its context is the emergence of the 15M, a citizen’s protest movement against the cuts imposed by the European Union and the Spanish Government. From a theoretical-methodological point of view, I adopt a holistic perspective, inspired by Halliday’s approach of jointly analysing the form-function relationship and White’s constructivism. I also review the different definitions and explanations of irony. After analysing the formal resources that construct irony, I give an account of the cognitive frameworks that are opposed in this discourse, and finally describe their narrative disposition and the communicative functions that those resources fulfill
