Decrease immigration to Spain  The Spanish possession of Ceuta and Melilla has resulted in an influx of illegal immigrants. Due to their positioning and membership to the EU, the two cities are subject to numerous attempts by immigrants to gain access to Europe1. In Melilla this has resulted in a social experiment with dire implications. To discourage illegal immigration, non-Moroccans who illicitly gain access to the country will not be permitted to move on from the city. They are trapped in Melilla without legal rights and generally live in extremely poor conditions with no means of legal work2. If the Spanish relinquished control of the two cities then these then there would be no permeable land border for illegal immigrants to gain access to.  1) Ribas,X. ‘The Border Fences of Cueta and Melilla.
