Anika Gauja examines the complexities and tensions in the relationship between party members and parliamentarians through an in-depth analysis of the structures and processes that shape the development of party policy, and the respective role of members and parliamentarians in the formulation of policy and its transferral to the legislative arena. Providing a timely contribution to the current scholarly and public debate on the future of political parties, the book presents significant new evidence on the challenges facing both established and emerging political parties in encouraging citizen participation in policy development and counters some of the overly simplistic judgments that are often made about participation and disengagement by revealing the complexity of the relationships that are involved in modern party systems.
