The GS made up part of the left wing of the party.
The GS was founded in 1988 to oppose the inclusion center-right politicians in the cabinet of president François Mitterrand.
[1] As part of the internal turmoil that followed the Socialist Party's first-round defeat in the 2002 presidential election, the GS began to disintegrate.
Mélenchon left the group and formed the Nouveau Monde ("New World") caucus.
Dray formed a new current that sought to reconstitute the party, Pour un Nouveau Parti Socialiste, but he later abandoned the idea and became an adviser to 2007 presidential candidate Ségolène Royal.
