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

In all of my speeches I talk about why a strong Europe is necessary in order for Germany to be strong over the long term. I think that I have sufficiently shown over the past years that I have a clear notion of how we can make Europe stronger, more democratic and more inclusive. There is really no competition there with Sigmar Gabriel.

We need to roll back precarious employment models. Temporary and limited contracts were initially seen as a way of introducing more flexibility so as to bridge periods of need in certain phases of production. Some employers have taken advantage of the model to push down wages. In general, we must strive for equal pay for equal work.

As a party of labor, the SPD must work together with the unions to ensure that people can make a living with their work. That is why I am not a proponent of the concept of unconditional basic income. I am, however, very much in favor of decent wage agreements, secure and lasting jobs, employee participation in decision-making and the examination of the social justification for claims and payments.

If we want to create new rules of globalization, then we can't just think in terms of the nation state. The nation state has long offered protection. But it suffers from the fact that many citizens increasingly fear that it can no longer protect them: The threat of transnational terrorism is growing. Freedom of movement rules in Europe facilitate social dumping. Regardless of the make-up of the next government, it must have clear ideas on how to overcome the lack of direction of recent years.

France is ready for a European revolution and it is Germany that is pulling the brakes. For a long time, it was the other way around. You don't have to agree with the details of every single one of Emmanuel Macron's suggestions, but he's right about the idea of a new foundation of Europe. Europe's Social Democrats have long demanded this. If we really want to, we can create a different, better Europe in the coming years.

We are in the middle of a tough, ideological conflict that is being waged across the entire continent. On the one side are those who say that global challenges like migration and terror cannot be met with national parochialism. On the other side are those who would like to see a renaissance of the nation-state.
