A pressure group is a group of people who share common interests and goals, and they work together to influence government policies. Therefore, the main objective of a pressure group is to influence the government to adopt policies or take actions that are in line with the interests and goals of the group. The group may lobby the government, organize protests, or engage in other forms of advocacy to achieve their objectives. The ultimate aim of a pressure group is to ensure that their interests and goals are represented and advocated for in government decision-making.
