Allan Greenspan said the eurozone needed "consolidation politically"
Former US Federal Reserve Chairman Alan Greenspan has said that a repeat of the crisis that brought the country close to default is "perfectly conceivable".
He told the BBC that he had not seen another situation in Washington where "compromise" seemed so far away.
