What are coalition governments and why are they often unstable?

Answer 1

A coalition government is a cabinet of a parliamentary government in which several parties cooperate. The usual reason given for this arrangement is that no party on its own can achieve a majority in the parliament.

To deal with a situation in which no clear majorities appear through general elections, parties either form coalition cabinets, supported by a parliamentary majority, or minority cabinets which may consist of one or more parties. Cabinets based on a coalition with majority in a parliament, ideally, are more stable and long-lived than minority cabinets. While the former are prone to internal struggles, they have less reason to fear votes of non-confidence. Majority government based on a single party are typically even more stable, as long as their majority can be maintained.

Answer 3

Not all coalition governments are unstable. That is apparent in a large number of such governments. The problems are more likely to come when the number of parties in an legislative body is simply too large and nothing can be done except informal alliances over one political problem, and soon after the parties separate. Because party alliances are so common, it can lead to confusion when parties split away from each other.
