The Nigerian Enterprises Promotion Decree of 1972, which was promulgated in Nigeria after the country gained its independence from Britain, put in place a framework for the varied transfer of equity ownership of expatriate businesses to Nigerians. The decree was replaced by a more stringent order in 1977. Despite the extensive research on the Nigerian indigenization episode, there have been few studies on the role of the British government in the entire exercise. This paper, using newly available evidence from the National Archives London, investigates the role played by the British government during the indigenization episode. Evidence in this paper suggests that the British government explored various strategies, orthodox and unorthodox, in its bid to protect British business interests in Nigeria during the period.
