The princess, familiarly known by the diminutive "Bunmi", was educated in England at a Christian girls boarding school, St. Mary's School at Hastings. She thereafter attended Pitman College, London. Emeka and Bunmi were married at the Anglican Cathedral Church in Lagos on 10 November 1962. In 1959, Emeka Anyaoku joined the Commonwealth Development Corporation. In early 1962, Anyaoku came in contact with the then Prime Minister of Nigeria, Sir Abubakar Tafawa Belewa. He had accompanied his visiting boss, Lord Howick, Chairman of the Commonwealth Development Corporation, to a meeting with the Prime Minister on the activities of the corporation in Nigeria and the West African region. The Prime Minister, impressed by Anyaoku's answers to some of his questions on the projects supported by the CDC in West Africa, took an interest in Anyaoku's future and persuaded him to consider joining the Nigerian Foreign Service. After a grueling interview by the Federal Civil Service Commission, he was offered an appointment in the Foreign Service in April 1962. Within a month of his entry, he was appointed Personal Assistant to the Permanent Secretary of the Ministry for External Affairs. There he was closely involved in the process that led to the establishment of the Organisation for African Unity (OAU) in May 1963. Following Nigeria's independence, he joined Nigeria's diplomatic service, and in 1963 was posted to its Permanent Mission to the United Nations in New York. In 1966, he joined the Commonwealth Secretariat as Assistant Director of International Affairs. In 1968-69 there was a campaign by the Nigerian military government for the recall of Anyaoku; which said he was not a suitable Nigerian nominee, and they were anxious about his loyalty "to the country of his birth". But "Emeka had resigned from the Nigerian Foreign Service and Arnold had no difficulty in turning aside the demand". In 1977, the Commonwealth Heads of Government elected him as Deputy Secretary-General. In 1983, Nigeria's civilian government appointed Anyaoku to become Nigeria's Foreign Minister. After the overthrow of the government by the military later that year, he returned to his position as Deputy Secretary-General with the support of the new government in Nigeria and the endorsement of all Commonwealth governments. At the Commonwealth Heads of Government Meeting at Kuala Lumpur on 24 October 1989, Anyaoku was elected the third Commonwealth Secretary-General. He was re-elected at the 1993 CHOGM in Limassol for a second five-year term, beginning on 1 April 1995.
