The relationship between a politician and his social addressee is a topical problem for democratic political systems built on a dialogue between government and society. This monograph analyses the phenomenon of response discourse generated by the social addressee as a reaction to the politician's discourse. The linguistic mechanisms that cause the emergence of response discourse space around a certain political discourse are considered. Theoretical model representing a particular political discourse and a set of response discourses as a spatially distributed system characterized by structural and cognitive unity is created. It is revealed that in British and American cultures response discourse is connected with political discourse in a predominantly negative way: it is mostly aimed at verification of politicians' insincerity and at negative axiological evaluation of their actions and personal qualities. The monograph is intended for general linguists and philologists.
