My only fight is for Paris. - Nathalie Kosciusko-Morizet

Have you ever tried to take the metro with a pushchair? I have two small boys. It's a nightmare, you can't replace that with a vélib [Mr Delanoë's bike rental scheme]. Lots of middle-class families with children are obliged to leave, due to economic and housing issues. The Left denies it, but more and more are going out to the suburbs.

I have always got on well with Rachida, She's someone who has all sorts of qualities, an incredible energy, an important presence. She leaves no one indifferent.

I don't buy the prevailing theory that capitals are becoming increasingly Left-wing, they are in full globalisation and reconstruction mode, with huge tectonic shifts, a fusion of cultures. Whoever has the vision and personality to run such world cities is the right person. It's less about the political card you carry.
