Political parties play an important role in supporting a democratic institution. Even in authoritarian countries, dictators need political parties to consolidate power and maintain governance. Without them, a country could not function healthily. However, there is growing discontent against “partisan politics” in some parts of the world. Similarly, some in Hong Kong do not want the Chief Executive to be a party member in the future. In light of the global trends and local debates, the first part of this paper argues that political parties have practical importance in operating and stabilising a democratic system, and they facilitate political bargaining which could effectively balance the interests of citizens. Discontent itself simply does not disregard the importance of the parties. The second part argues for a multi-party system through comparing the political consequences of it with one party and two-party systems in terms of the quality and the effectiveness of democracy.
