Former French Economy and Industry minister Emmanuel Macron (2nd-L) answers journalists as he arrives at the agricultural show of Châlons-en-Champagne on September 1, 2016. France's Emmanuel Macron vowed after stepping down as economy minister Tuesday to "transform" an ailing country but stopped short of declaring a presidential run. The 38-year-old said he had "seen at first hand the limits of our political system" and that quitting the government of President Francois Hollande would enable him "to be free" to push forward his own agenda. / AFP PHOTO / FRANCOIS NASCIMBENIFRANCOIS NASCIMBENI/AFP/Getty Images
