Former French Economy and Industry minister Emmanuel Macron (C)looks on during his visit of the agricultural shows of Chalons-en-Champagne, northeastern France, on September 1, 2016. Socialist Party (PS) secretary Jean-Christophe Cambadelis recalled that, as Arnaud Montebourg, a member of the party supporting Emmanuel Macron would be sanctioned or even excluded, according to the PS on September 1, 2016. A potential presidential bid by centrist former minister Emmanuel Macron has added to an already complex picture in French politics, with the left and right in turmoil eight months before the election. The 38-year-old Macron, who resigned as economy minister on August 30, 2016 to "begin a new stage in my fight" without yet declaring whether he will stand for president, would be a fresh face in a field of over-familiar candidates. / AFP PHOTO / FRANCOIS NASCIMBENIFRANCOIS NASCIMBENI/AFP/Getty Images
