Political communication is the transmitting of politically relevant information from one part of the political system to another, and between the social and political systems. Relevant information refers not just to factual matters about, for example, what has happened, but also to the transmitting of ideas, values, and attitudes. By definition communication is vital to all political and social behaviour; without communication there can be no politics and no society. Political conununication is the dynamic element of the political system. Karl Deutsch (1963) in his classic study The Neroes of GO'Demment places communication at the very heart of an understanding of politics.
