Pressure Groups are an increasingly important feature of the political landscape and they are active on many levels, local, national or European. They reflect a diverse compass of interests from the well-known (the National Farmers' Union) to the less familiar (the Zip Fastener Association) and interact with a wide range of political players in different parts of the political system: parties, the media, government and parliament. They are involved at every stage of the political process, from raising issues and agenda setting to policy implementation and monitoring.
