In some countries, there are only two main parties and power changes hands between them only. They are the only ones who can win seats in elections. There may be other parties and they may win a small number of seats, but never enough to form a government. The United States of America and United Kingdom are examples of two-party system. In a multi-party system, three or more parties have a chance to win elections and gain control of the government. In this system, there are more than two distinct, officially recognised groups called, political parties. In a multi-party system, groups come to power on their own strength or in alliance with others. In India various parties have come together in a coalition. In India,there have been three major alliances in the 2004 parliamentary elections as no single party got an absolute majority. This system is followed in India, France and Denmark. This system gives a chance to various interests and concerns, to gain representation.This system can sometimes lead to instability, as many parties cannot pull together.
