up of three or four arrondissements. The arrondissements are further divided in cantons, which are themselves made up of one or several communes. The communes and the départements have a local council elected by their citizens, but arrondissements and cantons are not run by elected officials. The cantons serve as an electoral district for the election of the département councils and arrondissements are run by a subprefect appointed by the French president. The president also appoints a prefect in each département. Because the départements are small and numerous, the French government tried to create wider regions during the 20th century. For the Breton nationalists, it was an occasion to recreate Brittany as a political and administrative entity, but the new region had to be economically efficient. Nantes and its département, Loire-Atlantique, raised concerns because they were off-centered, more integrated with the Loire Valley than with the Breton peninsula. The French government and local politicians also feared that Nantes, because of its population and its former Breton capital status, would have maintained a harmful competition with Rennes to get the regional institutions and investments. Several drafts for French regions had been proposed since the 1920s, and the definitive regions were drawn in 1956. The new Brittany had four départements, and Loire-Atlantique formed the Pays de la Loire region together with parts of Anjou, Maine and Poitou. In 1972, the regions received their present competencies, with an elected regional council. Since then, the region of Brittany has had its own council and administrative bodies. Reunification When the region of Brittany was created, several local politicians opposed the exclusion of Loire-Atlantique, and the question still remains. The obstacles to reunification are the same as in 1956: having Nantes in Brittany could harm the position of Rennes and create an economic imbalance between Lower and Upper Brittany. Moreover, the Pays de la Loire region could not exist without Loire-Atlantique, because it would lose its political and economic capital. Without Loire-Atlantique, the other départements would not form an efficient region any more, and would have to integrate neighbouring regions such as the Centre-Val de Loire and Nouvelle-Aquitaine. However, several institutions have backed the reunification, such as the regional council of Brittany since 2008 and the Loire-Atlantique council since 2001. Some politicians like Jean-Marc Ayrault, the former French prime minister and former mayor of Nantes, favour instead the creation of a "Greater West region", which would
