This is a very special Greek kind of socialist, all the social democratic parties in Europe are against this idea and I think that the dividing line today in the Greek political system is not the centre right or socialist, the real dividing line is between those parties and those political forces who really believe that Greece should stay in the Eurozone and make the efforts and change, and make the reforms and change the old and Mr Tsipras who is really resisting any kind of change in Greece.

You cannot walk away. The truth is that there is no magic way that you can say to your partners, "You are going to continue paying us the money and we will not keep our part of the deal." This is not possible around the world. It is good to hear it.

The interesting thing is that the 82% of the Greeks do not want to abandon the Euro. They really believe that there might be some kind of magical way where we could stay in the Eurozone but do not do our homework. This is not possible. So what we are trying to do is explain, you know, we in Greece invented democracy but we also invented at the same time populism.

We are neck and neck but there will be a very - it will be a very tough campaign in the last ten days. We must be very open and sincere with the Greek people. They should know what they could really expect. I think all of these old political logic is dead. We have to be honest, open and determined to get the Greeks out of this crisis.

There is no magic. Harry Potter was probably the last one. There are no Harry Potters in politics. There are people who should be hard working, admit their mistakes - and we made a lot of mistakes - make an honest self-critic but change what we did wrong. What did we do wrong? We built a state which is big, which is corrupted, which is a state which should radically change. What is Mr Tsipras saying - keep it as it is, so everything that is old belongs to him.

People are really in despair today in Greece. They are afraid of tomorrow. They suffer. We have 1.2 million people without jobs. So you understand that this crisis cannot leave the political system untouched. Of course we have to change but we have to change in the right way.
