Book excerpt: At a time of major changes in the United Kingdom and to a lesser extent in France, induced by the proposed Brexit process, this collective work – composed of thirteen chapters from highly experienced academics and specialist professionals from both sides of the Channel – examines their consequences on the French and British relationship in a range of institutional, political, legal, economic, cultural but also strategic and defence-related fields with an emphasis on comparative and/or European points of view. The two editors are respectively Associate Professors at Panthéon-Assas and Tours universities. Geraldine Gadbin-George is an English solicitor, a former avocat at the Paris bar and a former French judge. Elizabeth Gibson-Morgan is Visiting Senior Research Fellow at King’s College London in the Department of Contemporary History.
