This updated guide examines the different relationships between the various tiers of government in the UK and the EU, and how the EU's powers affect the UK, from a range of perspectives. It evaluates the role of the media, political parties, pressure groups, social media and the ever-changing position of public opinion, and places the relationship in its historical context to show how it has evolved over time. Each chapter includes an introduction, learning goals, a glossary, likely exam questions, helpful websites and suggestions for further reading. This new edition has two new chapters, 'Europeanisation' and 'The British Media and the EU', includes the fallout from the 2015 UK Parliament general election and the 2014 European Parliament election and draws on freshly updated examples, tables and figures updated throughout.
