In the United Kingdom, there is a balance of power between the chief constable, local government, and the Home Secretary. This balance of power is important in assuring that police forces are protected from central political direction, are accountable to the courts in exercising their powers, and are accountable to local and national elected representatives. The Police Service is dynamic in response to three clear pressures for change: (1) need for fiscal responsibility in all parts of the public sector, including the Police Service; (2) rising crime rates; and (3) increased public and government expectations for quality police services. New initiatives being pursued by the Police Service are described, including measures to enhance the quality of police services, improved police management methods, and activities of the National Criminal Intelligence Service. The structure and organization of European police cooperation are considered, particularly with respect to Europol and Interpol, and the importance of police reform to respond to political and social change in the United Kingdom is stressed.
