Supplementary text for a 1-term/semester undergraduate course covering European Politics (usually a year 2, 3 or MA option). The significance of British foreign policy in relation to Europe is wide-ranging, stretching from the grand policy of monetary union to the regulation of air quality. These developments span all government departments - European affairs does not, therefore, just fall under the responsibility of the Foreign and Commonwealth Office; policy-making and policy-implementation issues permeate into the wider body of domestic government departments, from Trade and Industry to the Treasury and Social Security to the Scottish Office. European and domestic foreign policy are no longer separate but intrinsically intertwined. This study promises to be an invaluable contribution to the subject, directing readers through the significance of European affairs to Britain, the manner in which decisions are taken and the likely developments in the future.
