Okay, so Mayotte is a small island located in the Indian Ocean, and it belongs to France. This means that France is in charge of making big decisions about how Mayotte should be run and what laws should be followed, but there are also people who live on Mayotte, and they have some say in what happens there too.
To help make these decisions, France has appointed a group of people called the French government to govern Mayotte. This group is made up of different leaders who are responsible for things like making laws, deciding how money should be spent, and solving problems that happen on the island.
However, because Mayotte has a unique culture and history that is different from mainland France, there are also local leaders on the island who have a say in what happens there. These leaders are elected by the people who live on Mayotte and are called the Institut d'Estudes Politiques de Mayotte or "IEP" for short.
So, in summary, France is responsible for making decisions about how Mayotte is run, but they work with local leaders to make sure that the needs and opinions of the people who live on the island are also heard and taken into consideration.
