Let's put it this way: I am confident that Schengen will continue to be defended. And when it comes to repatriations, we have the same opinion.

But joint pressure from states like Germany, Italy and France could mean a move in this direction. Because something very fundamental is on the line: freedom of movement. I can't think of any common market that could function without it.

We need to move forward, from the common currency to the banking union to a common financial policy and, in the middle-term, to a common foreign and security policy. That will take time, because we need to figure out how to deal with those countries that don't always want a more tightly integrated European Union.

But it could be that we, as early as spring, will need to embark on a new policy in order to save one of the cornerstones of European politics: personal freedom of movement.

We [European countries] probably need to move forward together, each at their own speed. The faster ones, that could be the countries in the euro zone. The others would be those who are interested in the continued development of the common market, but reject the idea of an ever stronger political integration.

The route for the refugees currently goes through Greece and the Balkans or through Italy; if there were a crisis in north-eastern Europe, Poland might just as well be affected. In this case we are dealing with mechanisms that we do not control. We need to change that.

We have a strong military deployment in Iraq and Afghanistan. In countries like Syria, we need a diplomatic breakthrough to end the war. In Libya, the country must first of all be stabilized to stop IS. This means supporting the Libyan government, including in terms of security. We don't want to repeat the mistakes of the past in that country. The situation is extremely dangerous and the next days could be decisive.
