Senegal President Bassirou Diomaye Faye on Friday sacked Prime Minister Ousmane Sonko and dissolved the government after months of tensions, deepening a crisis in the debt-laden west African nation. The shock announcement was made on state television in a decree read out by presidential aide Oumar Samba Ba, who said Faye "has ended the duties of Ousmane Sonko... and consequently those of the ministers and secretaries of state who are members of the government".

The once-unbreakable alliance between Senegal’s President Bassirou Diomaye Faye and his former Prime Minister Ousmane Sonko has collapsed. Their 2024 campaign slogan, « Diomaye Moy Sonko » (« Diomaye is Sonko »), symbolized their unity—but now, political rivalries and economic strain have driven them apart.

From allies to adversaries

Their partnership was forged to unseat former president Macky Sall (2012–2024). Yet barely two years into Faye’s tenure, the bond has frayed. Sonko, dismissed from his post on May 22, has returned to the political stage as Speaker of the National Assembly, making him the second most powerful figure in Senegal—and its most prominent critic of the president.

The fallout of power

Once inseparable, Faye and Sonko now embody opposing visions for Senegal’s future. The president’s decision to remove Sonko from the premiership marked the end of their collaboration. Sonko’s swift rise to the Assembly’s presidency underscores his defiance, positioning him as a constitutional successor—and a direct challenge to Faye’s authority.

The economic challenges facing Senegal have further strained their relationship. Fiscal pressures and policy disputes have exposed deep divisions, eroding the trust that once defined their alliance. What began as a united front against Sall’s regime now risks destabilizing Faye’s government.
