Politics
Politics of Ghana takes place in a framework of a presidential representative democratic republic, whereby the President of Ghana is both head of state and head of government, and of a pluriform multi-party system. The seat of government is at Osu Castle. Executive power is exercised by the government. Legislative power is vested in both the government and Parliament. The Judiciary is independent of the executive and the legislature. The head of state is President John Agyekum Kufuor, the ninth leader of the country since independence. The Parliament of Ghana is unicameral and dominated by two main parties, the New Patriotic Party and National Democratic Congress.
The Constitution that established the Fourth Republic provided a basic charter for republican democratic government. It declares Ghana to be a unitary republic with sovereignty residing in the Ghanaian people. Intended to prevent future coups, dictatorial government, and one-party states, it is designed to establish the concept of powersharing. One controversial provision of the Constitution indemnifies members and appointees of the Provisional National Defence Council (PNDC) from liability for any official act or omission during the years of PNDC rule. The Constitution calls for a system of checks and balances, with power shared between a president, a unicameral parliament, a council of state, and an independent judiciary.
