Ousmane Sonko, who was sacked as Senegal’s prime minister after a falling-out with President Bassirou Diomaye Faye, was re-elected Saturday as head of his Pan-African Pastef party. Sonko was also elected president of the country’s National Assembly shortly after his dismissal as prime minister. The rift between Sonko and Faye has plunged the West African nation into a political crisis.
