European Central Bank President Mario Draghi said that the euro was not in danger despite some analysts' worse case scenarios for a break-up and said that greater financial, budgetary and political union among eurozone countries was inevitable.

Asked in an interview with French newspaper Le Monde if the euro were in danger, Mr Draghi said: "No, absolutely not. We see analysts imagining the scenario of a euro zone blow-up."

"They don't recognise the political capital that our leaders have invested in this union and Europeans' support. The euro is irreversible," he added.

In the long term, the euro would need to rest on a foundation of greater integration among eurozone countries, Mr Draghi said.

"All movement towards financial, budgetary and political union is for me inevitable and will lead to the creation of new supranational bodies," he said.

European leaders took a step towards greater integration last month at a Brussels summit where they agreed to put the ECB in charge of supervising banks and gave the European Stability Mechanism rescue fund the power to recapitalise troubled banks.

Mr Draghi said that the ECB's monetary policy and bank supervisory activities would have to be kept separate in order to avoid conflicts of interest and suggested that an "independent structure" could be built.

The scandal over the fixing of the Libor rate was undermining confidence in a cornerstone of the global financial system, he said.

Turning to the economic outlook in the eurozone, Mr Draghi said he did not see the risk that the bloc as a whole would enter a recession and that the situation would gradually improve towards the end of the year and the beginning of 2013.

The ECB cut its interest rates to a record low earlier this month to breathe life into the ailing eurozone economy amid signs that inflation pressures were subsiding.

Mr Draghi said that the ECB, which strives to keep eurozone inflation at a rate close to but less than 2%, was prepared to take action in the case that the risk of deflation emerged.
