Europe has given the Greek government an ultimatum to produce a reforms-for-bailout cash package or face a eurozone exit. A deadline appeared as Sunday, when a new emergency euro summit will be held.

He has called all 28 European leaders to Brussels on Sunday, which could be the moment that Greece begins to leave the Euro.
