Consensus-building among the political parties on national critical issues is crucial for successful working of democracy. Parliamentary democracy is a very delicate system and it functions well in a society which has developed a kind of consensus in respect of use of power, acquisition of power, peaceful transfer of power and so on and also in respect of the key national issues. But “a great many of the developing countries, particularly those of Asia and Africa, but also some South American countries…..are beset by political problems arising from the deep division between segments of their populations and absence of unifying consensus.”[1]Likewise the political system in Bangladesh is seriously facing the crisis of consensus building.
