This chapter presents the basic model of parliamentary government. The discussion stresses the centrality of the cabinet and the role of party discipline in making that system stable. The general conclusion is that where it works, parliamentary government provides a clean, clear and efficient way of making policy. However, in cases where cooperative arrangements cannot be worked out within or among parties, the parliamentary system carries the danger of instability. The roles of parliaments in non-democratic systems are also discussed with special reference to the China's National People's Congress. The chapter ends with a detailed discussion of Germany and India.
