It officially abolished itself on 5 February 2009 to merge with smaller factions of the far-left and form a New Anticapitalist Party.
The group included members of other Trotskyist tendencies who were able to organise openly within its ranks to gain support for their views.
Its official spokespersons were Alain Krivine, Roseline Vachetta, who are former members of the European Parliament, and Olivier Besancenot who was the party's candidate for the presidential elections in 2002 and 2007.
In a situation where massive campaigns against government policy have brought millions into the streets, but established political parties have lost a lot of credibility, the idea of unifying the radical Left in an electoral alliance was much discussed.
The LCR campaign was run under the slogan "Beat Le Pen on the streets and in the ballot box".
However, as the party spent approximatively this sum, according to Pierre-François Grond, a member of the direction, it will not be financially affected by Besancenot's lower score.
