Mr Delors claims that the current crisis stems from “a fault in execution” by the political leaders who oversaw the euro in its early days. Leaders chose to turn a blind eye to the fundamental weaknesses and imbalances of member states’ economies, he says.

“The finance ministers did not want to see anything disagreeable which they would be forced to deal with,” he says.

The euro came into existence without strong central powers to stop members running up unsustainable debts, an omission that led to the current crisis. Now that the excessive borrowing of countries such as Greece and Italy has brought the eurozone to the brink of disaster, Mr Delors insists that all European countries must share the blame for the crisis. “Everyone must examine their consciences,” he says.
