Mark Corner has taught in universities in England, the Czech Republic and Belgium. He was also a Labour politician in local government from 1988-1992. For ten years he was a speaker in Brussels introducing the European Commission to groups of visitors. During his life he has become increasingly aware of the 'EU system' as a unique set of institutions that more than any other can help to curb the destructive effects of nationalism.

Brexit is a tale of two unions, not one: the British and the European unions. Their origins are different, but both struggle to maintain unity in diversity and both have to face the challenge of populism and claims of democratic deficit.
Mark Corner suggests that the »four nations« that make up the UK can only survive as part of a single nation-state, if the country looks more sympathetically at the very European structures from which it has chosen to detach itself. This study addresses both academic and lay audiences interested in the current situation of the UK, particularly the strains raised by devolution and Brexit.
