Before we talk about further accessions, we have to consolidate the European Union internally. People are increasingly losing faith in the EU's effectiveness.

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 EU is an unique project that replaced war with peace, hate with solidarity. Overwhelming emotion for awarding of Nobel prize to EU

We need a big debate in society about how we are going to shape Europe and tame capitalism. A government must provide direction and make concrete proposals. It is one of Angela Merkel's biggest failings that she doesn't do this.

When it comes to climate protection, the whole world will have to pay the price. But if Donald Trump intends to conclude a trade agreement with the EU, he will have to abide by our climate standards. In any case, waiving climate protection does not make American products more competitive.

I take note of the fact that there are a lot of people who appreciate what I do as parliament president, not just within my Social Democratic party group, but also among the conservatives.

Just come to Brussels after a Council meeting. Do you know what happens? Every head of government holds his or her own press conference. They all say the same thing, in 24 languages: I was able to push through my agenda. And if the result is anything other than what they desired, the message is: Brussels is to blame. It has been this way for over 20 years. These messages stick with people, and that's deadly for Europe.
