Why is Multiparty system is one of the weakest?

A multiparty system can be one of the weakest forms of governance because it often leads to political fragmentation, making it difficult to form stable governments. With numerous parties vying for power, coalition governments may be necessary, which can result in compromises that dilute effective policymaking. Additionally, this system can encourage extreme or fringe parties to gain representation, potentially leading to polarization and conflict within the political landscape. Ultimately, the lack of a clear majority can hinder decisive action and governance.
