Explanation:
The longest and most expensive military transition programme in Nigeria was under General Ibrahim Babangida. Babangida's transition programme, which was announced in 1986 and was supposed to end in 1990, was repeatedly extended and eventually lasted until 1993. It involved the creation of two political parties, the conduct of local government elections and the drafting of a new constitution. The programme was widely criticised for its length, cost and the manner in which it was manipulated by the military government.
