The executive branch of a government is responsible for implementing and enforcing laws, managing foreign relations, and overseeing national defense. Headed by the executive leader, such as a president or prime minister, this branch plays a crucial role in the day-to-day operations of governance. Additionally, it has the power to issue executive orders, appoint officials, and conduct diplomatic engagements. The effectiveness of the executive branch is vital for maintaining stability and addressing the challenges faced by the state and its citizens.
