At their 1998 Saint-Malo summit, the UK and French governments promised to set aside a century of rivalry and cooperate more closely on Africa. They also signalled their intention to develop a continent-wide focus on Africa, which would include building up the capacity of regional organisations. They were helped in this latter goal by the winding up of the OAU and its replacement by the AU in 2002. This article therefore examines the extent and nature of Anglo-French cooperation vis-à-vis the AU. It sets out briefly the history of UK and French neglect of the OAU, reviews the key developments that pushed for a more coordinated stance on the AU, and then – drawing on extensive interviews in London, Paris, Brussels, Addis Ababa and Dakar – evaluates the extent of Anglo-French cooperation. It concludes by noting the uneven nature of Anglo-French cooperation vis-à-vis the AU and assesses the reasons for this.
