The importance of executive power in governance lies in its ability to enforce laws, make decisions, and implement policies effectively. An executive branch led by a president or prime minister typically holds significant authority in shaping domestic and foreign policy. This centralized power allows for decisive action in emergencies and facilitates governance. However, a balance with legislative and judicial branches is essential to prevent abuse of power and ensure accountability. In a functional democracy, executive power is crucial for maintaining stability and addressing the needs of the population.
