Wolfgang Münchau writes: There is now a real possibility that the EU system for border and immigration controls will break down in about 10 days. On March 7, EU leaders will hold a summit in Brussels with Ahmet Davutoglu, the Turkish prime minister.

The action taken by Austria, Hungary and other countries to protect their national borders has shut the western Balkan route along which migrants had made their way to Germany.

Refugees now find themselves trapped in Greece. Some may leave for Italy by boat. When those who survive the journey arrive there, I would expect Slovenia, Switzerland and France to close their borders. At that point, we should no longer assume that the European Council of heads of government is a functioning political body.

A refugee crisis that spins out of control could tilt the vote in the British referendum. There is no way the EU will be able to deal with two simultaneous shocks of such size. Coming at a time like this, Brexit has the potential to destroy the EU.

I do not expect such a doomsday scenario, but it is not implausible either. The EU is about to face one of the most difficult moments in its history. Member states have lost the will to find joint solutions for problems that they could solve at the level of the EU but not on their own.
