French National Assembly deputy Nicolas Dupont-Aignan stands with his mouth covered with a scarf in the colours of the French national flag, during a debate about Libya at the National Assembly in Paris, in this July 12, 2011 file photo. A longtime eurosceptic and former member of President Nicolas Sarkozy’s ruling UMP party, Dupont-Aignan portrays himself as the only mainstream politician to advocate a French exit from the euro and a return of protectionism, an agenda he shares with Marine Le Pen’s far-right Front National.
