Coalition government arises when

A coalition government arises when no single political party has enough seats or majority in the parliament to form a government on their own. In such a situation, two or more political parties come together to form a coalition, where they work together to govern and pass legislation. This is done in order to gain a majority in parliament, so that the government can function effectively. Coalition governments are common in many countries around the world, and they can sometimes lead to compromise and cooperation between different political parties.
