Sandrine Berno Dos Santos

Sandrine Berno Dos Santos is the current mayor of Poissy, a town in the Yvelines department of France. She assumed the mayoral position in 2022 after Karl Olive, the previous mayor, stepped down upon his election to the National Assembly. Olive, a member of parliament and close to Emmanuel Macron, served as mayor from 2014 to 2022. Berno Dos Santos recently won reelection in the 2026 municipal elections, defeating Olive in his attempt to regain the mayorship. She is currently in the news because she has filed a complaint against Kentin Olive, Karl Olive's son, for alleged insults and threats. An investigation has been opened by the Versailles prosecutor's office into the matter of outrage against a person holding public authority. The situation highlights the ongoing political dynamics in Poissy and the tensions between Berno Dos Santos and the Olive family.
