Since taking office in March 2024, the alliance that brought the Pastef (African Patriots of Senegal for Work, Ethics and Fraternity) party to power has shifted. Bassirou Diomaye Faye and Ousmane Sonko are now locked in a political confrontation that is fundamentally altering the nation’s institutional landscape. Following Sonko’s departure from the Prime Minister’s office and his subsequent rise to the presidency of the National Assembly, Senegal has entered an unprecedented political era.

This new dynamic pits a president with significant constitutional authority against a popular political figure who leads the ruling party and commands a massive parliamentary majority. Political scientist Abdou Fattah Niane examines the tools available to both leaders and the elements that will shape this high-stakes power struggle.

What does the Faye-Sonko friction say about governance in Senegal?

There is no doubt that this is a full-blown crisis, particularly given it involves the Head of State and the former Prime Minister who now leads the legislative branch.

The tension between Diomaye and Sonko highlights the complexities of exercising power in the current climate. Historically, with the exception of the early post-independence years from 1960 to 1962, the Senegalese model has been characterized by a strong presidency supported by a parliamentary majority from the same party. We are now witnessing a functional cohabitation, which is a significant departure from the norm.

While it is too early to draw final conclusions as the situation continues to unfold, this period serves as a critical test of the resilience of the Senegalese political system. The ability of the state to navigate such internal friction will define its stability. This transition allows us to see if the system can handle a genuine division of power at the top or if it remains better suited for a centralized authority spanning both the executive and legislative branches. Ultimately, exercising power with moderation will be essential for maintaining national stability.

Is this a typical rivalry or a historical break for Senegal?

This situation represents a major rupture in the country’s political history. Since 1960, Senegal has only experienced one comparable institutional crisis that threatened national stability: the 1962 conflict between President Léopold Sédar Senghor and Prime Minister Mamadou Dia.

To grasp the current stakes, one must look at the context. The President of the Republic holds vast constitutional powers, including the right to define national policy. However, Ousmane Sonko was the one who selected Bassirou Diomaye Faye as the candidate and provided the vital support needed for his victory.

We are seeing a clash between two different types of legitimacy. On one side is the President’s legal and constitutional authority. On the other is the political legitimacy of a leader who controls the party machinery and enjoys deep-rooted popular support, as evidenced by the legislative election results in November 2024. The local elections scheduled for January 2027 will likely serve as a major turning point in this ongoing cohabitation.

What are the primary power bases for Faye and Sonko?

Both men are leveraging their specific positions to maintain influence. Ousmane Sonko relies heavily on the Pastef-Les Patriotes party, which reaffirmed his leadership during the June 2026 congress. Furthermore, he commands a dominant parliamentary majority with 130 out of 165 seats. This gives him significant leverage to monitor government actions, evaluate policies, and potentially initiate motions of censure.

Bassirou Diomaye Faye, while holding the extensive powers of the presidency, remains dependent on the National Assembly for various executive functions. Nevertheless, he wields the full weight of the state apparatus, and the symbolic stature of the presidency remains a potent resource in his favor.

Which factors will determine the outcome of this power struggle?

While the stakes are high, the political process is typically regulated by the electoral cycle. Elections act as a peaceful mechanism for correction. Moving forward, maintaining a consensus on the electoral calendar, ensuring transparency, and practicing restraint in both the executive and legislative branches will be vital.

Public perception regarding the governance styles of both Ousmane Sonko and Bassirou Diomaye Faye will be the ultimate deciding factor. The success of alternative public policies, the push for ethical leadership, and the public’s demand for accountability and justice for those killed during political unrest between 2021 and 2024 will influence the balance of power. While the party system and elections usually protect democratic stability, any lack of transparency or excessive use of power could potentially push the population toward collective action.
