Contributor(s): Enrico Letta | The referendum on the place of the UK within the EU is a unique opportunity to take stock of what isn't functioning in Europe, and to seek out a different track. It is not only in the UK that public opinion is turning towards euro-scepticism, as even in the most European of countries disarray and disappointment are rising. The reasons for this are diverse and run deep, but they must not be ignored, and this is why a discussion dedicated to the "big picture" must be preferred to a technical debate about details. A win-win solution would certainly be that of a "2-circle" Europe. Enrico Letta (@EnricoLetta) is the Dean of the Paris School of International Affairs (PSIA) at Sciences Po in Paris. He was the Prime Minister of Italy from April 2013 to February 2014. Before he served as Minister for EU Affairs (1998-1999), as Minister for Industry, Commerce and Crafts (January-April 2000, during the second D’Alema Government), as Minister for Industry, Commerce and Crafts and Foreign Trade (2000-2001, during the second Amato Government) and as Undersecretary of State to the Prime Minister of the centre-left government led by Romano Prodi from 2006 to 2008.
