Paris's left-wing parties, excluding La France insoumise, have approved a historic agreement to field a united list from the first round of the March 2026 municipal elections, backing Socialist candidate Emmanuel Grégoire.
On the evening of Wednesday, December 17, 2025, Emmanuel Grégoire, the Socialist Party (PS) candidate, hailed a 'historic moment' after Paris's left-wing parties, excluding La France insoumise (LFI), endorsed an unprecedented agreement. For the first time since 1977, when the capital's mayor was first elected by universal suffrage, the Socialists, Greens, and Communists are uniting from the first round for a joint candidacy to the Paris Council.
Following months of negotiations, the party leaders reached common ground on Tuesday evening. Parisian Green members approved the deal by 73.7% in an online vote on Wednesday, which their leader David Belliard, a 2020 candidate, called a 'vote of responsibility.' Among the Communists, led by Ian Brossat, approval reached 77.9%.
The agreement aims to strengthen the left ahead of the 2026 municipal elections, promoting values of social and popular ecology. Belliard celebrated the union as a way to 'make Paris a city proud of its values.'
