Brussels, January 15 - The eurozone economy is weaker than expected and stimulus is needed, European Central Bank President Mario Draghi told the European Parliament Tuesday. He said the ECB decied to end its QE bond-buying programme in December since it was "confident that the convergence of inflation towards the objective would continue". But now, he said, "there is no room for complacency". Draghi also said the eurozone had emerged from a crisis that had threatened its very existence thanks to the energy of European citizens. He said the confidence in pro-euro politicians must continue.
