The challenges of coalition government in politics include the potential for instability, as differing party agendas may lead to conflicts and inefficient governance. Additionally, coalition governments often involve compromise, which can dilute policy objectives and alienate party supporters. The necessity for consensus can slow down decision-making processes. In times of crisis, the inability to act decisively can exacerbate problems. Voter perception may also shift negatively if coalitions appear weak or unable to deliver on promises, thus affecting future elections.
