Reuters reports that all latest developments on Greek debt crisis has revived doubts about the long-term survival of the euro, nowhere more so than in London, Europe’s main financial center and a hotbed of Euroskepticism.

Objections on the 100-installement debt settlement expressed Euroworking Group president Thomas Wieser calling it an “unfortunate choice”.

Yanis Varoufakis told German business daily “Handelsblatt” that Greece would require a new international debt deal in order to meet obligations of almost 11.5 billion euros between June and August.
