semi-presidential system, also known as the French model. In this system, as in the parliamentary system, there are both a president and a prime minister; but unlike the parliamentary system, the president may have significant day-to-day power. For example, in France, when their party controls the majority of seats in the National Assembly, the president can operate closely with the parliament and prime minister, and work towards a common agenda. When the National Assembly is controlled by their opponents, however, the president can find themselves marginalized with the opposition party prime minister exercising most of the power. Though the prime minister remains an appointee of the president, the president must obey the rules of parliament, and select a leader from the house's majority holding party. Thus, sometimes the president and prime minister can be allies, sometimes rivals; the latter situation is known in France as cohabitation. Variants of the French semi-presidential system, developed at the beginning of the Fifth Republic by Charles de Gaulle, are used in France, Portugal, Romania, Sri Lanka and several post-colonial countries which have emulated the French model. In Finland, although the 2000 constitution moved towards a ceremonial presidency, the system is still formally semi-presidential, with the president of Finland retaining e.g. foreign policy and appointment powers. Parliamentary republics The parliamentary republic, is a parliamentary system in which the presidency is largely ceremonial with either de facto or no significant executive authority (such as the president of Austria) or de jure no significant executive power (such as the president of Ireland), and the executive powers rests with the prime minister who automatically assumes the post as head of a majority party or coalition, but takes oath of office administered by the president. However, the president is head of the civil service, commander in chief of the armed forces and in some cases can dissolve parliament. Countries using this system include Austria, Armenia, Albania, Bangladesh, Czech Republic, Germany, Greece, Hungary, Iceland, India, Ireland, Israel, Italy, Malta, Pakistan, and Singapore. A variation of the parliamentary republic is a system with an executive president in which the president is the head of state and the government but unlike a presidential system, is elected by and accountable to a parliament, and referred to as president. Countries using this system include Botswana, Nauru and South Africa. Dictatorships In dictatorships, the title of president is frequently taken by self-appointed or military-backed leaders.
