The French Republic is divided into 18 regions: 12 in mainland France and 6 elsewhere (1 in Europe: Corsica; 2 in the Caribbean (the Lesser Antilles): Guadeloupe and Martinique; 1 in South America: French Guiana; and 2 in the Indian Ocean near East Africa: Mayotte and Réunion). Territories of France, excluding Antarctic territories. Citizens from all these territories, including the overseas administrative divisions, are French citizens, vote in national elections (presidential and legislative), and all of the inhabited territories are represented in the Senate. The outcome could trigger government collapse, budget plan delays, or even snap elections. French Prime Minister François Bayrou will face a crucial confidence vote in parliament on 8 September.
