President Bassirou Diomaye Faye has initiated a sweeping overhaul of Senegal’s extractive industries, marking a clear departure from the political patronage that previously dominated state-owned enterprises. In a decisive move on July 1, 2026, the government announced sweeping leadership changes at Petrosen Holding and Somisen, two of the nation’s most critical economic institutions.
This strategic shift follows months of tension between the presidency and parliamentary leaders, particularly Ousmane Sonko, whose influence over key appointments has waned significantly since the start of the current administration. The changes signal a broader effort to depoliticize the extractive sector, prioritizing technical expertise over party loyalty in a bid to restore investor confidence.
New leadership takes charge
The shake-up saw Alioune Gueye, a long-standing coordinator for the Pastef party in the United States, replaced by Thierno Seydou Ly at Petrosen Holding. Similarly, Ngagne Demba Touré, former head of the Pastef youth wing, was ousted in favor of Mamady Touré at Somisen.
Sources within government circles revealed that both outgoing officials were notified of their dismissal through public announcements rather than direct communication from the presidency—a move that underscores the abruptness of the transition. « The decision was long overdue, but its timing caught many off guard, » commented an insider familiar with the restructuring.
End of an era for Pastef in public enterprises
While the presidency has not issued an official statement on the motivations behind the changes, observers note that the dismissals reflect deeper rifts between President Faye and Sonko. Gueye and Touré, both staunch supporters of Sonko, are seen as casualties of their allegiance to the parliamentary leader amid growing political friction.
This marks a stark contrast to the early days of Faye’s presidency in 2024, when Sonko was granted significant leeway to appoint Pastef members to high-ranking positions across ministries and state-owned corporations. The current restructuring, however, signals a decisive break from that approach.
The appointment of Thierno Seydou Ly at Petrosen Holding is particularly noteworthy, as it reverses a decision made by Sonko in March 2025 to remove Ly from his role at Petrosen Exploration-Production. At the time, Sonko sought to dismantle the leadership structures inherited from the previous administration under former President Macky Sall, clashing repeatedly with Gueye, who reported directly to him.
Technocratic leadership to reassure investors
In the midst of ongoing negotiations to revise extractive contracts signed under the previous government, President Faye is prioritizing technocratic leadership to stabilize the sector. While Gueye and Touré held backgrounds in accounting and law respectively, their successors bring specialized technical expertise to their roles.
Thierno Seydou Ly, a petroleum engineer with prior experience at TotalEnergies, now leads Petrosen Holding, while Mamady Touré, a geologist and former head of a specialized engineering and training firm, oversees Somisen.
« The new leadership is expected to adopt a more diplomatic and less divisive approach in their dealings with international partners, » noted a source close to the administration. The move is widely seen as an effort to reassure foreign investors amid ongoing contract revisions and to signal a commitment to professionalizing the sector.
As the presidency continues to reshape the governance landscape, further changes may be on the horizon. Other high-profile figures with close ties to Sonko, including Waly Diouf Bodiang, director general of the Port autonome de Dakar, and Fadilou Keïta, head of the Caisse des dépôts et consignations, could also face leadership transitions in the coming months.
