Coalition is an act of coalescing or uniting into one body or a union of parties. When different political forces join together,coalition is formed. Coalition politics is a system of governance of a group of political parties or by several political parties.

Merits of coalition are as follows:

It provides broader representation to the people as big and small parties join hands in the governance. It also enables them to have a share in policy making and eliminates regional disparities.

1. It provides an opportunity for the creation of consensus based politics which represents the public opinion in national politics, issues and programmes. As M.A. Jinnah said a coalition is a device to provide a fair share to the minority. 

2. Coalition takes care of diversity and plurality in administration. 

3. By feeling the pulse of people, it provides good governance. 

4. The presence of various political parties provides broader choice for the people to elect. 

5. Coalition does not allow the autocratic rule of a single dominant party. Ministers or members of Cabinet including Prime Minister cannot behave autocratically.
