A court in Senegal is due to announce a verdict shortly in a rape trial against the opposition leader, Ousmane Sonko.
The capital, Dakar, is braced for potential violence.
The politician’s supporters say the case is aimed at stopping Mr Sonko from standing in presidential elections next year.
He has repeatedly denied wrongdoing and has urged people to “rise up”.
When Mr Sonko was arrested in 2021 clashes left at least a dozen people dead.
He has accused Senegal’s president, Macky Sall, of planning to stay in office for an unconstitutional third term.
