Arnaud Deslandes Elected Mayor of Lille, Succeeding Martine Aubry

The long-time collaborator of Aubry takes over as Lille's leader, facing challenges ahead of the 2026 municipal elections.

Arnaud Deslandes officially became Lille's mayor on March 21, 2025, following a municipal council vote where he secured 43 out of 54 votes.
Deslandes succeeds Martine Aubry, who stepped down after 24 years as mayor, citing the need for generational change in leadership.
A loyal collaborator of Aubry since 2005, Deslandes has held various roles, including first deputy mayor, and played a key role in Lille's urban transformations.
His appointment is seen as a strategic move to boost his visibility and position him for the competitive 2026 municipal elections.
Critics question Deslandes' leadership style and lack of electoral experience, with challengers like Stéphane Baly and Roger Vicot already preparing campaigns.
