A prime minister is the head of a cabinet and the leader of the ministers in the executive branch of government, often in a parliamentary or semi-presidential system. A prime minister is not a head of state or chief executive officer of their respective nation, rather they are a head of government, serving typically under a monarch in a hybrid of aristocratic and democratic government forms.
In parliamentary systems fashioned after the Westminster system, the prime minister is the presiding and actual head of government and head of the executive branch. In such systems, the head of state or the head of state's official representative (often the monarch, president, or governor-general) usually holds a largely ceremonial position, although often with reserve powers.
In many systems, the prime minister selects and may dismiss other members of the cabinet, and allocates posts to members within the government. In most systems, the prime minister is the presiding member and chairman of the cabinet. In a minority of systems, notably in semi-presidential systems of government, a prime minister is the official who is appointed to manage the civil service and execute the directives of the head of state. Template:Executive
The prime minister is often, but not always, a member of the Legislature or the Lower House thereof and is expected with other ministers to ensure the passage of bills through the legislature. In some monarchies the monarch may also exercise executive powers (known as the royal prerogative) that are constitutionally vested in the crown and may be exercised without the approval of parliament.
As well as being head of government, a prime minister may have other roles or posts—the Prime Minister of the United Kingdom, for example, is also First Lord of the Treasury and Minister for the Civil Service. Prime ministers may take other ministerial posts. For example, during the Second World War, Winston Churchill was also Minister of Defence (although there was then no Ministry of Defence) and in the Thirty-fourth government of Israel (2015-2019)[update], Benjamin Netanyahu at one point served as Minister of Communications, Foreign Affairs, Regional Cooperation, Economy, Defense and Interior.
