Barre was a candidate in the 1988 presidential election, yet, despite his popularity, he was not supported by all UDF personalities. Giscard d'Estaing himself refused to choose clearly and publicly between his two former Prime Ministers. Eliminated in the first round, Barre called on his supporters to vote for Chirac in the second round, but despite this, Chirac was defeated by Mitterrand. After the re-election of Mitterrand, some UDF members participated as ministers in the left-wing cabinets of Prime Minister Michel Rocard. Others created a new parliamentary group, the Centrist Union, which occasionally voted with the Socialist Party or with the RPR.
