Opposition Political Parties and Democratization in Africa: A Study in Profundity is a unique publication on all aspects, trends, theories, processes, principles, roles and the philosophy of opposition political parties in the stability, sustenance and legitimacy of democratic systems with particular reference to Africa and more deeply Nigeria, where the idea of opposition political parties has not been well assimilated, grounded and appreciated as government in the waiting or an alternative government. This current edition as entitled is a deepened, profound, and all-encompassing analysis and exegesis; a scholarly and profusely masterpiece on the earlier edition with additional five chapters among which is the inevitability of shadow government in the constitutionality, authenticity, institution and leveling of democratic governance for all shades and opinions. It is this missing link which African politicians are yet to grapple with that has left ruling parties hegemonic, becoming authoritarian and even autocratic as opposition political leaderships abandon their camps and hence their responsibility to join forces with the ruling parties once the elections are over through decamping, carpet-crossing, vagrancy, defection and apostasy thereby creating vacuum as the balancing factor, the defender of the minority, oppressed, and defenseless citizens. The book is decidedly to awaken the consciousness and yearnings of Africans on the importance of opposition political parties in the stability and enhancement of political process in all democratic dispensations.
