Coalition government

A coalition government, or coalition cabinet, is a government where political parties enter a power-sharing arrangement of the executive. Coalition governments usually occur when no single party has achieved an absolute majority after an election. A party not having majority is common under proportional representation, but not in nations with majoritarian electoral systems.

There are different forms of coalition governments, minority coalitions and surplus majority coalition governments. A surplus majority coalition government controls more than the absolute majority of seats in parliament necessary to have a majority in the government, whereas minority coalition governments do not hold the majority of legislative seats.

A coalition government might also be created in a time of national difficulty or crisis (for example, during wartime or economic crisis) to give a government the high degree of perceived political legitimacy or collective identity, it can also play a role in diminishing internal political strife.

In such times, parties have formed all-party coalitions (national unity governments, grand coalitions). If a coalition collapses, the Prime Minister and cabinet may be ousted by a vote of no confidence, call snap elections, form a new majority coalition, or continue as a minority government.
