In 2007, Nicolas Sarkozy, former President of France and, at this time, President of the Hauts-de-Seine Departemental Council near Paris, launches a new project: the Grand Paris. It is a mix between critics of what is called in France politique de la ville (city policy), the political orientation of the previous left government (1997-2002) and orientations of local authorities who are managed by the left. He draws a very negative representation of suburbs, as the outcome of a decadent past, with an uncertain future and the reflection of the present crisis of our society. By studying debates in the French National Assembly and Nicolas Sarkozy's discourses, I will demonstrate the opposition of a model coming from the Western Parisian region (his political fief) and another coming from the Northern part (the poorest). Moreover, this communication will present an alternative vision of the Grand Paris project, to enlighten ideological opposition, since Nicolas Sarkozy imagine Paris through the London's paradigm.
