Officials in Germany and France are reported to be mulling a radical overhaul of the European Union towards a more economically integrated – and perhaps smaller – euro zone.
Speaking on condition of anonymity, a senior EU official in Brussels told Reuters that France and Germany had had “intense consultations on this issue over the last months, at all levels".
