In politics, the opposition comprises one or more political parties or other organized groups that are opposed, primarily ideologically, to the government (or, in American English, the administration), party or group in political control of a city, region, state, country or other political body. The degree of opposition varies according to political conditions – for example, across authoritarian and liberal systems where opposition may be either repressed or desired respectively.
