Key takeaways
- A pressure group tries to influence policy without seeking to govern; a political party contests elections to hold office. The competition between such groups is what makes a democracy pluralist.
- Sectional groups defend their own members' interests, such as the BMA for doctors; cause groups campaign for a belief, such as Extinction Rebellion. Insider groups are consulted by ministers; outsiders are not.
- Success depends on insider status, resources, expertise, public sympathy and whether a group is pushing in the same direction as the government of the day.
- The Snowdrop Campaign got the first handgun ban passed within a year of Dunblane and the rest within two; the Countryside Alliance drew around 400,000 marchers in 2002 and still lost, because the government opposed it.
- Think tanks supply research and policy ideas, lobbyists are paid to put a client's case to decision-makers, and corporations add the economic weight of their investment and employment decisions.

Key terms
- Pressure group
- An organised body that seeks to influence government policy or public opinion on particular issues without putting up candidates to form a government itself.
- Sectional group
- A group that exists to protect the shared interests of a defined section of society, usually recruiting only from that section.
- Cause group
- A group that campaigns for a belief, value or wider public benefit rather than for the material interests of its own members.
- Insider group
- A group whose expertise or standing earns it routine consultation by ministers and civil servants before decisions are taken.
- Outsider group
- A group without regular access to decision-makers, which therefore works through publicity, protest, petitions and litigation.
- Access point
- A place in the political system where an outside group can bring influence to bear, such as a government department, a Commons committee, a court or a devolved administration.
- Pluralist democracy
- A democracy in which many organised groups compete for influence and no single interest dominates, so policy emerges from the contest between them.
- Elitism
- The view that political power in practice rests with a small, well-connected minority, so open competition between groups is more apparent than real.
- Think tank
- A research organisation that studies policy problems and publishes proposed solutions, aiming to shape what governments and parties believe is possible.
- Lobbyist
- Someone whose paid job is to win favourable decisions for a client by putting that client's case directly to the people who write, pass or apply the law.
- Corporation
- A large business whose size gives it political weight, used to press for conditions friendly to business generally or for rules that suit its own sector.
Frequently asked questions
Insider groups are consulted directly by ministers and civil servants and work through quiet negotiation; outsider groups lack that access and rely on publicity, protest, petitions and the courts. Status can change: a group can be granted or lose access when the government changes.
A sectional group represents the interests of its own members, so membership is usually restricted, such as the BMA for doctors. A cause group campaigns for a belief or a wider public good and is open to anyone who shares it, such as Greenpeace.
Both arguments have force. They disperse power, supply expertise and represent people between elections. Against that, the best-resourced groups win most often, and unelected groups can obstruct a policy a government was elected to deliver.
