A coalition government is a common feature of a multi-party system. In a multi-party system, there are usually more than two parties with no party winning an outright majority. In such a scenario, parties may form a coalition government to achieve a majority and gain control of the government. A coalition government is formed when two or more political parties come together to form a government. Each party in the coalition agrees to share power and work together on certain policies and agendas. This arrangement helps to promote political stability and encourages consensus-building among different political parties.
