ABSTRACT
David Easton, unlike many other political scientists, does not take as his starting point the analysis of power in political systems. Easton’s work again provides a valuable point of reference, and his analysis of political activity in terms of systems theory may help to clarify the complex range of phenomena under investigation. One of the key processes of political systems is inputs, which take the form of demands and supports. The organisation of British central government can be described simply. General elections, which must be held at least every five years, result in the election to the House of Commons of some 650 Members of Parliament. Ministers are responsible for day-to-day running of the government’s business through the major departments of state. These departments include Treasury, which is responsible for all matters to do with finance, and Department of Health and Social Security.
