# 2020 Ain municipal elections

The 2020 Ain municipal elections took place on 15 March 2020, with a second round of voting initially expected for 22 March 2020. Like the rest of France, the second round was initially suspended due to the COVID-19 pandemic. On 22 May, Prime Minister Édouard Philippe announced that the second round of voting would take place on the 28th of June.

## Incumbent and elected mayors

The election was marked by political stability, with the right remaining largely the majority political force in the department. The left, having largely been defeated in 2014, was unable to regain seats lost in Ambérieu-en-Bugey, Attignat, Belley, Ferney-Voltaire, Montluel, Ornex, Prévessin-Moëns, Trévoux and Villars-les-Dombes. In 2020, the left continued its political erosion by losing seats in Miribel and Reyrieux, but was consoled with the re-election of Jean-François Debat (PS) in Bourg-en-Bresse.
