The eurozone can't allow any country to blackmail it with the threat of financial contagion, the chief of Germany's Bundesbank Jens Weidmann said on Friday, two days before a Greek election that will decide if the debt-laden country will stick to the strict terms of its EU/IMF bailout deal.

"In any case, we must not allow any country to blackmail us with the consequences of contagion," Weidmann, who is also a member of the governing council of the ECB, was quoted as saying in an interview with Greek newspaper Kathimerini.
