In politics, there are different categories of friendship. My friendship with Greek Prime Minister Alexis Tsipras, for example .

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 good thing about the European Union is that the joint project ultimately benefits all Member States and not just a few.

With their charm and legendary sense of humor, the British directly or indirectly paved the way for a large number of European compromises.

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.

You can't have euro bonds without more interconnection among the national budget policies.

The use of EU summits to frame political victories or defeats is an annoying habit.
