BRUSSELS - Former European Central Bank (ECB) chief economist and German central banker Otmar Issing has warned that the eurozone may split up - another voice in the chorus talking about a Greek exit from the common currency.
"Everything speaks in favour of saving the euro area. How many countries will be able to be part of it in the long term remains to be seen," Issing wrote in his latest book, entitled: "How we save the euro and strengthen Europe."
