Lobbying in the United Kingdom
Formal procedures enable individual members of the public to lobby their Member of Parliament but most lobbying activity centres on corporate, charity and trade association lobbying, where organisations seek to amend government policy through advocacy. Companies and individuals who operate in this sector commonly use the terms "public relations", "public affairs", "political consultancy" or "corporate affairs" to describe their activities (though this was also a reaction to the negative publicity surrounding the word "lobbyists" following the 1994 Cash-for-questions affair). Professional public affairs agencies, representing multiple clients, undertake a significant proportion of lobbying activity in addition to individual organisations conducting lobbying on an in-house basis.
Public policy
As an academic discipline, public policy brings in elements of many social science fields and concepts, including economics, sociology, political economy, social policy, program evaluation, policy analysis, and public management, all as applied to problems of governmental administration, management, and operations. At the same time, the study of public policy is distinct from political science or economics, in its focus on the application of theory to practice. While the majority of public policy degrees are master's and doctoral degrees, there are several universities that offer undergraduate education in public policy.
