This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book provides an analysis of the economic relationship between Britain and the European Union (EU) and thereby facilitates discussion of the future direction in which this relationship might develop. It examines the consequences that might arise if Britain withdrew from the EU, either to be free of the costs and restraints imposed by membership, or through desiring to create different forms of trade and/or macroeconomic strategy aimed at more optimally promoting national economic development than under the current EU model. The importance of the EU for British economic development has, additionally, been called into account due to the increasing impact of globalisation. Neo-liberal conservatives may support the creation of a large free trade area, free from all political interference with the agenda of big business, but may oppose most forms of regulation and discussion of political integration that originate in Brussels.
