Political parties are central to India political life. Their role in political mobilization, governance, the formulation and implementation of economic and social policy, ethnic conflict, separatist movements, and the working of democracy has long been the focus of analysis. Their centrality arises from the fact that they are the key link between individual and state, and state and society as staed earlier. Political parties provide the crucial connection between social process and policy makers, and influence debates and policies on issues affecting the interests of various social groups in the political system. As more and more people participated in the democratic process, competitive politics and the party system have undergone a major change over the past two decades. The Congress and the ruling BJP led National Democratic Alliance face dissension at all levels extending from differences between the BJP and organizations it is affiliated with, such as the Rashtriya Swayam Sevak Sangh (RSS) and the Vishwa Hindu Parishad (VHP), and between the party and its coalition partners.
