 However, after Jean-Luc Mélenchon was elected to the European Parliament after the 2009 elections, he vacated his seat in the Senate on 7 January 2010, and after Autain lost his seat in the Senate in the renewal of seats during the senatorial elections on 25 September 2011, the group reverted to its original name.On 19 September 2012, Nicole Borvo Cohen-Seat resigned from the Senate, and was succeeded by Eliane Assassi, who was elected president of the CRC group the same day.The group was renamed to the Communist, Republican, Citizen and Ecologist group ("groupe communiste, républicain, citoyen et ecologiste") after the 2017 renewal, when it was joined by the ecologist senators Esther Benbassa, Guillaume Gontard, and Pierre-Yves Collombat.
