Senegalese President Bassirou Diomaye Faye is preparing to launch his own political party, instructing senior adviser Aminata Touré to lead a task force to create the new movement — the clearest sign yet of a lasting rupture with former Prime Minister Ousmane Sonko, his one-time ally. Faye dismissed Sonko in May after months of deteriorating relations; Sonko has since become Speaker of the National Assembly and is pushing constitutional reforms that would, among other changes, bar a sitting president from leading a political party — amendments Faye has chosen to put to a national referendum rather than sign into law. The deepening rivalry plays out against a backdrop of economic strain and looming 2027 local elections that will serve as a key test of each leader's political support.
