Coalition governments are politically unstable. It can also called as political arranged system. In this system, no party gets the absolute majority and formed the government with the help of various political parties by making common agenda. Due to the presence of various parties believing in different ideologies and policies, political consistency is difficult to achieve.

Here the leader of the coalition government has to compromise with all the allies partners, otherwise they will withdraw their support for simple reason often and often. The leaders of the coalition government have lost the power in the coalition politics since 1977 for several times. For example the first coalition government which came to power in 1977 under the leadership of Morarji Desai lost the power within 2 years.

In the same manner Y.P. Singh who ’lead the National Front in 1989 lost the power within 20 months. Like wise H.D. Devegowda formed the coalition government in 1996 loses the power with in 10 months. So coalition government cannot be in power for full term.
