As overseas departments of France, Guadeloupe and Martinique are governed by officials appointed by the French government. They do not have their own Prime Minister or President. The highest-ranking official in each department is known as the Prefect, who is appointed by the French President. The Prefect is responsible for overseeing the implementation of French policies and representing the French government in the territories.
