Positive effects :

• Public Support : 

Instead of council of a party, the council of coalition supports the opinion of the Council of Ministers. The higher the number of parties involved in the coalition, the equalization of the people gets the support of the government. 

• Avoiding Extremist View Point : 

The politics of coalition can prevent extremist ideologies, as any of the constituent parties can try to block its approach. No party in coalition can impose only its policy and principles because other parties in the coalition can oppose this. 

• Creating Strong Opposition : 

One benefit of coalition politics is also that one political party cannot resist such a strong opposition of the ruling party which can be done by alliances of several parties. When UPA was the coalition government then the NDA coalition was effectively able to oppose of the government. 

• Governance is not autocratic : 

The Prime Minister does not dominate the coalition council as powerfully as when one party is in the government. The council of Minister has to work on the basis of a minimum common programme. The council of Ministers cannot work arbitrarily. The Prime Minister has to keep in mind the principles of the policies of all the parties involved in the coalition. 

• The contribution of qualified people of the country : 

In a single-party government, people from the same party hold all portfolios, there is no contribution from the people of the other parties. In the event of coalition, the eligible people of all the parties involved in the coalition are taken in the council of Ministers. The advantage of the contribution of the senior and qualified people of all the parties is received by the country. By an increased scope of the formation of the council of Ministers, the more qualified people join the council of Minister.
