Géraldine Bannier joined the Democratic Movement (MoDem) in 2007 and was soon elected to the party's national council. She was Jean-Noël Martin's designated substitute in his unsuccessful campaign to represent the Canton of Saint-Berthevin in the 2011 cantonal elections, with their ticket winning 7.48% of the vote.[2] Three years later, in the 2014 French municipal elections, Bannier was elected mayor of Courbeveille as part of a nonpartisan electoral list.[3]
In 2018, Bannier became the vice-president of the parliamentary commission investigating the Lactalis affair, where the eponymous company's baby formula was found to be contaminated with Salmonella.[13]
In 2019, Bannier broke ranks with her government and parliamentary group by voting against the ratification of the Comprehensive Economic and Trade Agreement (CETA) free trade agreement.[14]
In 2020, Bannier abstained in a vote on the Global Security Law during its first reading but ultimately voted in favour of the law in April 2021.[15][16]
Bannier also served as the spokesperson for a bill aiming to impose a minimum fee for book deliveries.[17]
Bannier was re-nominated by the governing coalition, now known as Ensemble, for the 2022 French legislative elections.[18][19] She was nevertheless opposed by Christophe Langouët, the mayor of Cossé-le-Vivien, who also declared his support for the presidential majority.[20] Bannier was ultimately re-elected to the National Assembly with nearly 59% of the vote in the second round against the New Ecological and Social People's Union's Grégory Boisseau, who received 41%.[21]
