(i) They represent some common or general interest that needs to be defended. The Bolivian organisation, FEDECOR is an example of this kind of group.
(ii) In some instances, the members of a public interest group may undertake activity that benefits them as well others. For example, BAMCEF (Backward and Minorities Community Employees Federation) is an organisation largely made up of government employees that campaign against caste discrimination.

sectional interest groups seek to promote the interests of a particular section or group of society.Their principal concern is the betterment and well-being of their members, not of society in general.Public interest groups aim to help groups other than their own members.They promote collective rather than selective good.

Both pressure groups and movements attempt to influence the government's policies rather than directly take part in electoral competition.but unlike the pressure groups, movements have loose organisation.They depend much more on spontaneous mass participation than an interest group.

Pressure groups are important in the functioning of a democratic government as they provide an opportunity for marginalised people to voice their opinions.In some cases, the government's opinion might be biased by a small group of rich and powerful people.It is here that pressure groups step in and force the government to make policies which will benefit certain other sections of society as well.

(ii) Political parties sometimes grow out of movements.Parties like DMK and AIADMK were formed this way.
(iii) Many a times, the issues raised by pressure or movement groups are taken up by political parties, leading to a change in the policies of the parties.
