I try to speak in a manner that allows people to tell me apart from my political adversaries. And I speak in a manner that the people can understand. For me, that isn't populism.

I find it surprising, however, that many German politicians generally oppose referendums, but then when it's an EU matter, they immediately scream for a plebiscite.

It's not attractive at the moment to vouch for the European idea. I still do it, because I believe nothing would be better for our continent.

Political leaders need to formulate long-term EU goals that show: Yes, we want to stay together.

Germany is not a fair country. Millions of people believe that things aren't fair in this country. Company profits and bonus payments have increased at the same rate as precarious employment situations.

Complementing the nation-state as it reaches its limits amid globalization: That is what Europe must offer.

Would I sacrifice a friendship to take a step forward in my political career? Thus far in my political career, I have been spared from having to make such a decision, thank God. And I can't imagine what it must be like.
