Power dynamics shift in coalition governments due to the necessity of collaboration among multiple parties. Each party must negotiate and compromise to achieve a functional majority, often leading to policy concessions and altered agendas. This can create a balance of power, where smaller parties gain influence, requiring larger parties to consider diverse viewpoints. Such shifts can affect legislative outcomes, speed of governance, and party stability. Additionally, coalition dynamics can lead to political fragility if disagreements arise, impacting the government's overall effectiveness and longevity.
