[9][10] However, a faction of ex-PRG members, including its last president Sylvia Pinel, split from the Radical Movement in February 2019 due to its expected alliance with La République En Marche in the European elections and resurrected the PRG.

Robert Fabre sought to attract left-wing Gaullists to the party and gradually became close to President Valéry Giscard d'Estaing, who nominated him as Mediator of the Republic in 1978.

In the 1984 European elections, the MRG formed a common list with Brice Lalonde's environmentalists and Olivier Stirn, a centre-right deputy.

[12] The party resumed its customary alliance with the PS in the 1986 legislative election and supported President Mitterrand's 1988 reelection bid by the first round.

In the 2002 presidential election, the PRG nominated its own candidate, former MEP and French Guiana deputy Christiane Taubira, for the first time since 1981.

However, some members of the party including Émile Zuccarelli and PRG senator Nicolas Alfonsi supported Jean-Pierre Chevènement's candidacy.

Six deputies (Gérard Charasse, Paul Giacobbi, Annick Girardin, Joël Giraud, Dominique Orliac and Sylvia Pinel) and three senators (Jean-Michel Baylet, André Boyer and François Vendasi) opted to vote in favour, hence allowing for its passage.

Although the PRG remained a close and loyal ally of the PS, it has also cooperated with the small Ecology Generation (GE) party since December 2011.

In the 2017 SP presidential primary, PRG candidate Sylvia Pinel received 2% of the vote in the first round election held on 22 January 2017.

In the 2017 French legislative election, the party only re-elected three MPs; Annick Girardin, Jeanine Dubié and Sylvia Pinel.

In metropolitan France, the PRG was able to sustain a long-lasting Radical tradition dating back to the French Third Republic, most notably in the southwest or departments such as the Eure-et-Loir and Eure.
