Involve
Involve’s mission is to put people at the heart of political decision-making. They define themselves as a public participation charity to develop, support and campaign for new ways to involve people in decisions that affect their lives.
Since 2003, Involve has been working with governments, parliaments, civil society, academics and the public to create and deliver new forms of public participation that revitalize democracy and improve decision-making.
