Less than a month after reshuffling the government and removing Ousmane Sonko from the Prime Minister’s office, President Bassirou Diomaye Faye continues tightening control over critical state institutions. A recent leadership overhaul at Petrosen Holding and Somisen marks a decisive pivot toward technical competence over partisan loyalty.
On July 1, 2026, the President executed a strategic overhaul of the boards of the Senegalese National Petroleum Company (Petrosen Holding) and the Senegalese Mining Company (Somisen). The changes reflect a broader recalibration of governance priorities that has begun to reshape the nation’s economic landscape.
At Petrosen Holding, Alioune Gueye has been succeeded by Thierno Seydou Ly, while Ngagne Demba Touré made way for Mamady Touré at Somisen. “The axe was inevitable; only the timing remained uncertain,” confided a close advisor to the administration.
According to associates of the outgoing leaders, “they learned of their removals through the press, without prior notification from the presidency.”
End of partisan influence in public enterprises
While the presidency has not issued an official statement on the rationale behind these appointments, the shift aligns with broader tensions between President Faye and the National Assembly President. Insiders suggest that Alioune Gueye—former coordinator of the Pastef party in the United States—and Ngagne Demba Touré, ex-leader of the party’s youth wing, “paid the price for their allegiance to Ousmane Sonko.”
This stands in stark contrast to 2024, when President Faye granted Ousmane Sonko broad discretion to appoint party loyalists to ministerial and public enterprise roles. The move also carries political significance: in March 2025, Sonko had attempted to remove Thierno Seydou Ly from leadership of Petrosen Exploration-Production, seeking to dismantle appointees from the previous administration under President Macky Sall. Tensions reportedly ran high between Sonko and Alioune Gueye, who served as his direct supervisor.
Technical expertise to bolster investor confidence
Amid ongoing renegotiations of extractive contracts inherited from the prior government, President Faye appears to be prioritizing technocratic leadership over political affiliation. While Alioune Gueye held credentials as a chartered accountant and Ngagne Demba Touré as a legal expert, their successors bring deep technical experience to their roles. Thierno Seydou Ly, an oil engineer with a background at TotalEnergies, now leads Petrosen Holding, while Mamady Touré, a geologist and former head of an engineering consultancy specializing in geosciences and mining, oversees Somisen.
The strategic intent is clear: signal stability and professionalism to foreign investors while advancing contract negotiations. “The new appointees are known for their measured, diplomatic approach in engagements with international partners,” noted a senior official familiar with the process.
The reshuffle also raises questions about future targets. Given their close ties to Ousmane Sonko, Waly Diouf Bodiang, Director General of the Autonomous Port of Dakar, and Fadilou Keïta, head of the National Deposits and Consignments Fund (Caisse des Dépôts et Consignations), “could be next in line for leadership changes.”
