In Europe, even more so than in national politics, we have to follow the principle laid down by Martin Luther: Use language that the people will understand, but don't just tell them what they want to hear.

I am for it - not to make a threat, but to make clear that decisions that have been made are applicable law, even if you have voted against it. At issue here is European solidarity, which cannot be a one-way street. The traffic has to move in both directions.

In the highest government office, you have to be ready to bow out at any time, otherwise you are not a free individual anymore.

The way some German politicians have lashed out at Greece when the country fell into the crisis has left deep wounds there. I was just as shocked by the banners of protesters in Athens that showed the German chancellor in a Nazi uniform.

Since populists never miss an opportunity to create a lot of noise about anti-Europe stance. However, the repercussions of the British referendum could quickly put a stop to such crass rabble-rousing, as it should soon become clear that the UK was better off inside the EU - economically, socially and in foreign policy terms.

Greeks have to know that they are not alone ...

Greece is a member of the EU and the euro. I want Greece to be a constructive member of the Union because the EU is also benefiting from Greece.
