A political seismic event of unprecedented scale has profoundly impacted Senegal and the wider sub-region. On Friday, May 22, 2026, President Bassirou Diomaye Faye officially terminated the mandate of his Prime Minister and political mentor, Ousmane Sonko. This drastic action leads to the immediate dissolution of the cabinet and signals an abrupt conclusion to the executive partnership that had guided the nation since the change of power in April 2024.

Decree No. 2026-1128: The official declaration of separation

The shockwave reverberated across the nation that evening with the release of a significant official document. The Head of State, President Faye, formally signed presidential decree number 2026-1128 on Friday, May 22, 2026, instantly ending Ousmane Sonko’s tenure as head of government. To formalize this split, Bassirou Diomaye Faye meticulously invoked the powers vested in him by Senegal’s fundamental law, specifically referencing Articles 42, 43, 53, and 56 of the Constitution.

This legal framework establishes the President of the Republic as the guardian of the Constitution, ensuring the proper functioning of state institutions, and granting him the discretionary authority to appoint and dismiss the Prime Minister. Article one of the decree unequivocally states, “The functions of Mr. Ousmane Sonko, Prime Minister of the Republic of Senegal, are hereby terminated.”

According to Article 2, the decision takes immediate effect. Through a constitutional ripple effect, the departure of the head of government automatically triggers the resignation of all ministers and secretaries of state. However, the decree specifies that outgoing cabinet members are tasked with managing current affairs until a new ministerial team is appointed.

“Diomaye is Sonko”: The genesis of an unprecedented partnership

To fully grasp the magnitude of this political upheaval, it is crucial to recall the exceptionally close and unique relationship that bound the two leaders. Ousmane Sonko, the charismatic figurehead of the PASTEF party, had spearheaded a fierce opposition against the Macky Sall administration. Confronted with relentless legal challenges and his ultimate disqualification from the presidential race by the Constitutional Council in early 2024, Sonko made a brilliant strategic move.

While sharing a prison cell following a series of political arrests, Ousmane Sonko had designated his Secretary-General and most loyal lieutenant, Bassirou Diomaye Faye, as the substitute candidate for their systemic reform agenda.

Driven by the memorable slogan “Diomaye is Sonko,” the substitute candidate became the embodiment of popular enthusiasm, leveraging the party leader’s strong base. Released under an amnesty law just days before the election, the two men conducted a lightning-fast campaign, culminating in Bassirou Diomaye Faye’s triumphant first-round victory on March 24, 2024.

Immediately following his swearing-in on April 2, 2024, the newly inaugurated President appointed Ousmane Sonko as Prime Minister via decree n°2024-921. This marked a historic moment in African politics: a political mentor becoming the institutional subordinate of his own protégé, establishing an unprecedented dual-headed governance structure.

Seeds of discord: From fusion to friction

While the illusion of perfect harmony was sustained for an extended period through public statements, the realities of state power quickly exposed the limitations of this two-headed operational model. Over the months, it became clear that two subtly divergent visions were clashing.

On one side, Ousmane Sonko maintained his core identity as a sovereignty theorist and orator, frequently delivering direct and decisive statements on international issues, the renegotiation of mining and oil contracts, and a potential break from traditional partners. Conversely, President Faye found himself directly facing the practicalities of macroeconomic management, regional diplomacy, and the absolute imperative to reassure financial markets.

The initial visible cracks emerged during the governmental reshuffle on September 6, 2025, formalized by the signing of decree n°2025-430, which outlined the new cabinet composition. Far from easing tensions, this reshuffle highlighted internal power struggles for control over key ministries between the Prime Minister’s long-standing loyalists and the technocrats favored by the Head of State.

In essence, this political cohabitation, featuring a President of the Republic holding constitutional legitimacy and a head of government embodying historical popular legitimacy, reignited the “kingmaker” dynamic. This created a highly unstable balance where Ousmane Sonko’s persistent influence over presidential decisions ultimately brought the question of actual authority at the pinnacle of the Republic to a head.

What lies ahead for Senegal?

This dismissal propels Senegal into an entirely uncharted political landscape. By asserting full control over the state apparatus through this authoritative act, President Bassirou Diomaye Faye definitively frees himself from the moral oversight of his former leader. He now assumes the complete authority of his presidential office alone.

The significant unknown now lies in the stance Ousmane Sonko will adopt. Will the PASTEF leader opt for silence, a gentle separation, or a return to outright opposition, bolstered by his still highly active electoral base? The composition of the upcoming government, anticipated in the coming hours, will offer crucial insights into the new direction President Faye intends to steer his mandate.
