Coalition governments can have mixed effects on political stability. On one hand, they allow for a broader representation of interests, which can lead to more inclusive policymaking. When diverse parties collaborate, it can foster dialogue and compromise. However, coalition governments can also be unstable due to differing ideological agendas, leading to potential gridlock or frequent changes in leadership. This instability can undermine public confidence in government effectiveness and may lead to snap elections. Ultimately, the effectiveness of a coalition depends significantly on the parties' willingness to cooperate and the stability of their agreements.
