I spoke with Gerhard Schröder about a lot of things, including foreign policy. Schröder knows how important European policy is to me personally. I have worked together with Angela Merkel on European policy for many years, so I was surprised when Volker Kauder who has little experience in European policy, claimed that I had not represented German interests in Europe. That's an example of how the conservatives conduct an election campaign.

I believe that dignified work is a value in itself.

CDU head Angela Merkel has tried for years to serve two sides: the conservative side by holding up her CDU party membership. But then at the same time she acts as though she were also a Social Democrat. I don't have this hydra-headed nature. In the end, people will vote for the Social Democratic original.

We all have to accept accusations that we ignored the refugee crisis for far too long. The first time that I referred to the Mediterranean Sea as Europe's cemetery was in October 2013, when hundreds of people drowned off Lampedusa. Italians, Maltese, Greeks and Spaniards have been pleading for help for years. But nobody cared.

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.

For German Social Democracy, Europe is vital to the national interest.

There you see how absurd the reactions of the so-called markets are. For a long time, Italy was run by one of the most unprofessional politicians anywhere. But there wasn't much pressure in terms of speculation. Now, in Mario Monti, Italy has the kind of leader you usually only get in Hollywood movies, a distinguished professor who won't even accept a cook at his residence, the Palazzo Chigi. Instead Monti's wife cooks their pasta herself - and this is the man the markets don't trust.
