I'm not a populist. But I try to present complicated issues in such a way that people know where I stand.

Donald Trump has made the principle of purposely breaking a taboo into a means of achieving his political objectives, which is something that he has in common with Turkish President Recep Tayyip Erdogan and Hungarian Prime Minister Viktor Orbán. Trump systematically violates international rules. But we cannot allow ourselves to forget that Trump is not the U.S.

We must now, in the 21st century, protect democracy, one which rests on fundamental rights for all, regardless of skin color, gender, race or religion. Nothing less than that is at stake.

For me, respect is an extremely important political term. Since I began campaigning, it has been at the heart of each of my speeches. Many people have the feeling that politicians aren't paying a sufficient amount of attention to them. And then, when the refugees arrived on top of all problems, there was a feeling: You do everything for them, but nothing for us. This mixture of frustration and fear has led to this reaction. That is why it is so important to show these people: We respect you.

If you say in advance there is going to be a main candidate and then that doesn't count later, then that's going to be a highly problematic occurrence in a democracy.

I am critical of the fact that Hungarian Prime Minister Viktor Orbán is pulling out of everything - the joint approach to the refugee issue, for example. He cannot disparage his colleagues in the EU either - that's not how we treat each other. We require solidarity: in refugee policies, just as in the financial architecture of the structural funds from which countries like Hungary have strongly profited from for years.

Turkey has in interest in finding agreement on more permissive visa requirements, it wants to be recognized as a safe country of origin and it wants to finally return to constructive EU accession negotiations. We Europeans decide all of those things together.
