This article assesses the “business of development” in the post-colonial age, when bilateral and multilateral aid regimes offered businesses new opportunities. It uses the case study of Britain and the European Economic Community (EEC), from Britain's accession to the EEC in 1973 to the early 1980s, to demonstrate that the British government viewed multilateral aid instruments, in particular the European Development Fund (EDF), as offering commercial opportunities for British firms. Based on records of the EEC, business associations, and the French and British states, the article analyzes business-state relationships between national governments, corporations, and supranational institutions. As the UK government tried to redirect EEC aid toward places where its firms had the most to gain, it met the opposition of other member states and European institutions as well as the disinterest of its own businesses.
