This book examines how the implementation of the EU Regional Policy supports the multi-level governance theory.It deals with the subject areas of devolution, aspects of recent Welsh politics, and concepts of multi-level governance.Its analytical focus around the multi level governance themes highlights how the multiple levels that characterise the new political landscape enhance the role of sub-national authorities at the EU level.It discusses the theoretical and empirical literatures on Wales as a nation' and also the current debates about governance' in the context of European integration. It contains an analysis of the position of Wales in the UK's post-devolution governance, with an up-to- date treatment of the most recent developments in the on-going devolution process in Wales. The conclusions drawn in the book are based on the findings from a mixture of extensive interviews and documentary analysis, and offers a useful summary of the empirical findings.It concludes that the potent mixture of devolution and EU Regional Policy has produced a new form of multi-level governance in Wales and realigned the British political landscape.
