Ousmane Sonko, an opposition politician, lost his appeal against his defamation conviction before Senegal’s Supreme Court, which could jeopardize his chances of contesting the presidential election. “The fines and sentencing have been verified. After a hearing that lasted more than 12 hours, the judge decided to uphold the six-month suspended sentence. “Sonko lost on all counts,” state attorney El Hadji Diouf declared on Friday.Sonko was “now totally banned from taking part in an election,” he continued. While incarcerated last month, the 49-year-old submitted his nomination paperwork in order to run in the elections scheduled for February 25. Sonko was removed from the nation’s voter records and sent to jail following his arrest on insurrectionary charges in July. He has been involved in several judicial matters.
