Corruption charges against former French president Nicolas Sarkozy linked to the financing of his successful 2007 election campaign have been dropped, judicial sources told AFP on Monday. Sarkozy had been charged in March with accepting funds from France\'s richest woman, L\'Oreal heiress Liliane Bettencourt, when she was allegedly too frail to know what she was doing. The decision to drop the charges could clear the way for Sarkozy to return to frontline politics in time for the 2017 presidential election.
