In the 2026 municipal elections, Karim Bouamrane, representing the Socialist Party, was declared the winner in Saint-Ouen-sur-Seine, securing 56.44% of the votes. His main competitors included Manon Monmirel from the Unsubmissive France party, who received 28.2% of the vote, and former UDI mayor William Delannoy, who garnered 15.35%. Bouamrane’s victory not only reflects political support within the community but also underscores his position as a significant political figure since being one of the first mayors of Maghreb origin in a large French city over 50,000 residents.
