On 17 December 2017, at the congress of the Democratic Movement (MoDem), Christophe Castaner said he supported an "enlarged list" for the European elections based on their alliance,[11] and on 26 September 2018, the movement officially announced the opening of applications for prospective candidates from civil society,[12] receiving 2,673 in total,[13] winnowed by an investiture committee chaired by Jean-Marc Borello.

[14] Former Élysée advisor Stéphane Séjourné was designated campaign director on 29 October, tasked with creating a list alongside Agir,[15] and seeking a lead candidate with a "green profile".

On 15 February, Challenges revealed that EELV MEP Pascal Durand would be on the list in an electable position and Séjourné in the top 25 places.

[28] In an interview published in Challenges on 6 February, Radical Movement co-president Laurent Hénart indicated that the movement would likely vote to join a common list,[29] sparking dissent among some ex-PRG members including co-president Sylvia Pinel, who announced her departure from the party to resurrect the PRG on two days later.

François Bayrou, the leader of the Democratic Movement (MoDem) has previously proposed the formation of a coalition that would include centrist and centre-right parties.

In November 2021, president of the National Assembly, Richard Ferrand, accepted his proposal and together they had formed Ensemble Citoyens for the upcoming 2022 legislative elections.

[46][47] From its foundation in November, the coalition has been headed by Ferrand as its leader, Bayrou and Édouard Philippe as vice-presidents, and Stanislas Guerini as secretary-general.

The coalition aimed to bring the presidential majority of Emmanuel Macron together in order to present its joint candidates for the 2022 French legislative election.

[72] Some media sources consider it as a modern incarnation of Valéry Giscard d'Estaing's Union for French Democracy (UDF), founded in 1978.
