In 1958, the Southern Cameroons attained the status of a full region and became autonomous and fully self-governing. Dr. Endeley's official title accordingly changed to that of Premier (Prime Minister). In 1957, United Nations Resolutions 1064 (XI) of 26 Feb 1957 and 1207 (XII) of Dec 13, 1957 called on the Administering Authorities to hasten arrangements for Trust territories to attain self-governance or independence. In 1958 the House of Assembly and the House of Chiefs called for complete separation from Nigeria and total independence. In 1959 the opposition party Kamerun National Democratic Party (KNDP) won elections making it the first time in Africa that power changed hands peacefully from a government in power to an opposition party. John Ngu Foncha leader of the KNDP became the second Premier (Prime Minister) of the Southern Cameroons9. Furthermore, United Nations' resolutions 1350 (XIII) of March 13, 1959 and 1352 (XIV) of October 16, 1959 called on Britain, the Administering Authority to organize a plebiscite in the Southern Cameroons under UN supervision based on the following two 'alternatives': independence by joining Nigeria as one of the autonomous regions of that country or French Cameroun in a federation of two states, equal state in status. In 1960, the Westminster Parliament in London enacted a constitution for the Southern Cameroons known as the Southern Cameroons (Constitution) Order in Council. The Constitution put in place a full-fledged parliamentary and ministerial system of government modelled after that of the United Kingdom. This constitutional measure was taken contemporaneously with the separation of the Southern Cameroons from Nigeria. The Southern Cameroons attained the status of a full self-governing Territory though still a United Nations Trust Territory under Britain.
