Russian opposition leader Alexei Navalny has been found guilty in the retrial of his 2013 fraud case, according to reports. The verdict means that 40-year-old Navalny, who was accused of embezzling about $500,000 worth of timber, cannot run for president in the next election, potentially going up against Vladimir Putin. A prior verdict in the matter was overturned by the European Court of Human Rights, which found that Navalny had been denied the right to a fair trial. Navalny, a leader behind anti-corruption campaigns and anti-government protests in recent years, has not yet been sentenced. Navalny has said the case is a sham and an effort to keep him from running in an election.
