A Prime Minister is the most senior minister of cabinet in the executive branch of government in a parliamentary system. In many systems, the prime minister selects and can 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.
