Which type of pressure group actively seeks to influence government policies?

Insider pressure groups are organizations that work within the political system and have established relationships with policymakers, facilitating direct access to influence government decisions and legislation. They often possess expertise, credibility, and resources, allowing them to provide valuable information and insights that can shape public policy in their favor. These groups typically have a strategic approach to advocacy, engaging in discussions, consultations, and negotiations with government officials to push their agenda.

In contrast, outsider pressure groups may not have direct access to policymakers and rely on public campaigns and grassroots efforts to sway opinion and pressure the government indirectly. Volunteer and informal pressure groups do not fit the same mold as insider groups, as they may lack the established connections or structured approach that characterize insider groups. Thus, the emphasis on influence through well-established channels and relationships makes insider pressure groups the correct answer in this context.
