Greece operates as a parliamentary republic with executive power shared between the president and the government. The Government of the Hellenic Republic directs national policy through a 20-member cabinet officially called the Ministerial Council. The president appoints the prime minister, who must maintain the confidence of parliament. Headquartered at Maximos Mansion in Athens, the government functions through multiple specialized bodies, including the Committee on Institutions and the Government Council for Foreign Affairs and Defence. This system balances centralized authority with democratic accountability to the Hellenic Parliament, creating a governance framework that manages both domestic and international affairs.
