The notion of ‘responsible government’ that underpins the Westminster system of parliamentary democracy is intimately intertwined with political parties, as the executive arm of government must command the confidence of the lower chamber of Parliament which in effect compels the executive to rely on the support of the political parties that represent the electorate. The tremendous impact of political parties in their relation to responsible government was perhaps most sensationally evident in the events surrounding the successful 1979 motion of no confidence in the British Labour government of James Callaghan; this motion, which passed by merely one vote, was conducted almost entirely along party lines which demonstrates that political parties are in practice the most fundamental and important unit of organisation towards determining the nature and composition of the government.

Conversely, critics of the close relationship between pressure groups and political parties assert that in many cases the will of the people as expressed through elections is undermined
