I have always said I will be in politics to serve as best as I can and it will take me wherever it will take me.

If Greece had gone through a very normal political life, I may have not been in politics. But just the fact that I lived through huge upheavals and very difficult struggles and polarization and the barbarism of dictatorships - that made me feel that we had to change this country.

There is this concept of politics as a dirty game. It's a difficult game, but it doesn't have to be dirty. I think this is what we need to bring to politics. I think politics around the world has very often been captured by big interests - 'lobbies' they call them in the States.

The fact that we're going through a crisis is an opportunity for Europe to be more coordinated and more integrated. We're actually talking about a European Monetary Fund or euro bonds, about guarantees for countries, about economic governance in the European Union. That shows the strength of Europe.
