The latest paroxysm of Greece’s debt crisis has exposed growing rifts in the euro zone which, unless addressed soon, could lead to the break-up of European monetary union, the EU’s most ambitious project.

There are so many stakeholders with divergent views that crisis management is becoming ever more difficult.
