French president Francois Hollande arrives at the EU MED Mediterranean Economies summit in Athens on September 9, 2016. With France's Francois Hollande and Italy's Matteo Renzi in attendance, the gathering comes less than two weeks after rescuers saved a one-day record of 6,500 migrants making the perilous journey across the Mediterranean to Europe. The four-hour conclave is also a chance to craft a common platform ahead of the major summit in Bratislava next month to chart the union's post-Brexit future. / AFP PHOTO / LOUISA GOULIAMAKILOUISA GOULIAMAKI/AFP/Getty Images
