In 1995, after many attempts, Serge Dassault (RPR) captured the town of Corbeil-Essonnes. The billionaire used his colossal fortune to shower the city with millions of euros.

Part of this money was used to buy the elections. Bruno Piriou (DVG), who, after the death of Dassault in 2018, took the reins of the city in 2020. The city of Essonne, led since 2020 by the left, is trying to move away from clientelism.
