The aim of the study is to build a model of political discourse to describe its place in the taxonomy of discursive practices from the perspective of linguistics. The scientific novelty lies in identifying the characteristics of political discourse not as a separate type of discourse, but as a meta-discourse combining several types of discourse at its various levels and covering many spheres of human activity. As a result of studying the definitions of the term political discourse and the existing classifications of discourses, a nuclear-peripheral model of political discourse has been proposed, which consists of four shells, where the central place belongs to political communication as a tool of struggle for political power, academic political discourse is located in the nuclear zone, public political discourse is found in the near periphery of the model, while the periphery of the model includes the discourse of recipients of political messages. The paper describes the correlations of the shells of the model of political discourse with other types of discourse, such as ideological, legal, social, economic, mass media, artistic, business, academic, virtual, scientific, conversational and everyday discourse.
