Pressure-group activity has increased in the British Parliament in recent years. This study examines the activities of pressure groups in relation to individual MPs, legislation, select committees, party and all-party subject groups, political consultants, and the House of Lords. The essays adopt a broad definition of the term to include groups such as trade unions and business and professional organizations, as well as those bodies specifically created to exert political pressure. Providing a comprehensive picture of pressure-group activity in relation to Parliament, this book places it within the wider context of pressure politics in Britain today.
