Europeans have deep doubts about euro

Analyst Simon Tilford, chief economist at the CER said such a scenario cannot be ruled out. "If a country were to opt to leave the eurozone, the rest of the eurozone would have to make sure that process was a relatively controlled one… the problem with that is the smoother the transition into non-euro status, the greater the attractiveness of that option for other eurozone economies. And therefore, it risks a sort of knock-on effect, a chain effect," said Tilford.
