Senegalese voters go to the polls in delayed presidential election

Senegal goes to the polls on Sunday to vote for its fifth president in a delayed election being held against a turbulent political backdrop which has triggered violent anti-government protests and boosted support for the opposition. Nineteen contenders are vying to replace President Macky Sall, who is stepping down after a second term marred by violent unrest over the prosecution of firebrand opposition leader Ousmane Sonko and concerns that Sall wanted to extend his mandate past the constitutional limit. The incumbent is not on the ballot for the first time in Senegal's history.
