I'm not 100% sure on your answer,but I know this: Parliamentary system, democratic form of government in which the party (or a coalition of parties) with the greatest representation in the parliament (legislature) forms the government, its leader becoming prime minister or chancellor. A parliamentary system of government means that the executive branch of government has the direct or indirect support of the parliament. ... The head of government is the prime minister, who has the real power. The head of state may be an elected president or, in the case of a constitutional monarchy, hereditary.
