(ANSA) - ROME, APR 22 - Problems won't wait for the EU to solve them, President Sergio Mattarella said Monday, speaking from Brdo on the occasion of the 20th anniversary of Slovenia's entry into the European Union. "Among the essential reforms awaiting the European Union there are certainly the modes of decision-making, because problems in this world present themselves quickly and require timely responses: the European Union is not in this condition, it is not in a position to take timely responses because problems do not wait for the times of this Europe," he said.
