Валь-д’Аран
According to some Iberists, the Federation or Confederation should be formed by the peninsular parts of Portugal and Spain (without the Aran Valley, which should belong to Gascony), the Balearic Islands, Gibraltar, Andorra, and the Basque and Catalan regions of France. Four languages should be official: Castillian, Galician-Portuguese, Catalan and Basque.
