Europe was founded as a community bound together by solidarity.

The membership survey was a great moment for inner-party democracy. We can't go back, nor do we want to. Our members are pouring their hearts into this campaign. But people don't join the Social Democrats party just to put up posters. They join because they want to help steer the party.

We have committed ourselves to pursue joint policies, but then national governments say, "We aren't bound by that." That is a dramatic situation, because solidarity is a basic principle that cannot be had on an à la carte basis. If we have rules that nobody adheres to, then the community will break apart.

The old fundamental principles must continue to apply, even in our changing society: Democracy knows neither master nor slave. Equal education opportunities for all, no matter where they come from and no matter who their parents are. Equal access as well when it comes to digitalization.

We won't get any growth in Greece by just imposing cuts. What I would prefer is a special economic zone for Greece.

If Merkel has discovered Europe in a beer tent, I can only say: better late than never. Otherwise, it was the height of hypocrisy: The chancellor sat down for a beer with CSU Chairman Horst Seehofer, the man who after the election praised Donald Trump as a very resolute man.

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.
