Question

what do you mean by pressure groups or interest groups​

Answer 1

Interest groups are large category of organizations that are formed to promote a special interest. Interest groups technically include pressure groups, and the general public is usually most familiar with the lobbying sector of pressure/interest groups. However, interest groups can be separated from pressure groups as organizations that are concerned with an interest other than coercively influencing policy

Pressure groups are a specific sector within interest groups. These organizations use persistent and coercive techniques to affect policy and influence policymakers. Pressure groups are always political in nature and are generally advocacy or lobbying firms or organizations.

Answer 2

Explanation:

A pressure group is an organised group that seeks to influence government (public) policy or protect or advance a particular cause or interest. Groups may promote a specific issue and raise it up the political agenda or they may have more general political and ideological objectives in mind when they campaign.

Pressure groups operate at

Local

Sub National (Regional)

National

International level (including European Union)

Interest or pressure groups are formed by people to protect or advance a shared interest

Like political parties, groups may be mass campaigning bodies

However while parties have policies for many issues and, usually, wish to form a government, groups are essentially sectional and wish to influence government only on specific policies
