The Greek government operates as a parliamentary republic, where the President serves as the head of state and the Prime Minister is the head of government. The government is divided into three branches: the executive, legislative, and judicial. The Hellenic Parliament is responsible for making laws and consists of 300 members elected by the public. Elections are held every four years, and political parties play a significant role in the governance process. The Constitution of Greece outlines the rights and responsibilities of citizens and the structure of the government, ensuring a democratic framework for the nation.
