There should be no big catastrophes from stress tests on European banks but the reviews should be tough, the chairman of euro zone finance ministers, Jean-Claude Juncker, was quoted as saying.

I am not expecting any big catastrophes, he told Austrian newspaper Kurier. But there cannot be any glossing over, the tests are based on reality, he said in an interview published on Friday.

He also said that the euro is not in danger and that no country wanted to leave the euro zone.
