Abstract
Brexit has been a game-changer for Britain, and its key partners. Strategic shifts as well as historic relations have impacted the UK’s relationship with France in a number of unexpected ways. This article explores some of the key historical events that have caused both agreement and strife between the two states, looking at the bilateral treaties established to deepen cooperation on security and defence, specifically the Lancaster House agreements, and considers the series of intriguing accords and conventions that have arisen from the mid-1980s, as well as the logistical challenges of the shared border and juxtaposed border controls of Britain and France. Post-Brexit diplomatic forums in which Britain and France are joined by Germany are then explored, before assessing Britain’s attempts to forge its new role in relation to long-standing commitments to France and an evolving relationship with the EU.
