This Briefing Paper considers how Brexit will impinge on the African, Caribbean and Pacific (ACP) countries currently governed by the Economic Partnership Agreements (EPAs) negotiated by the EU. The authors explore whether the new Brexit-induced frictions on UK-EU trade will reduce the demand for ACP inputs – such as Cocoa products – into the goods that the UK and EU trade with each other. They conclude that the economic effects of even a ‘No Deal’ Brexit on ACP countries’ trade will be tiny in aggregate, because ACP countries supply only small amounts of inputs into the products involved in UK-EU trade.
