Louis Viannet spectacularly quit the national bureau of the PCF in 1996 and Bernard Thibault, the CGT's leader between 1999 and 2013, left the PCF's national council in 2001. "L'Humanité" has retained closer ties with the PCF. The newspaper was founded by Jean Jaurès in 1904 as the socialist movement's mouthpiece, and it followed the communist majority following the split in 1920. After having been the official newspaper of the PCF, with a readership of up to 100,000 in 1945, the newspaper's readership and sales declined substantially partly due to the PCF's concomitant decline. In 1999, the mention of the newspaper's link to the PCF was dropped and the PCF no longer determines its editorial stance. It sold an average of 46,929 newspapers per day in 2012; down from 53,530 in 2007. Secretaries-general (1921–1994) and national-secretaries (since 1994)  There are no formal organized factions or political groupings within the PCF. This was originally due to the practice of democratic centralism, but even after the democratization of the PCF structure after 1994 the ban on the organization of formal factions within the party remained. According to party statutes, the PCF supports the "pluralism of ideas" but the right to pluralism "may not be translated into an organizations of tendencies". Nevertheless, certain factions and groups are easily identifiable within the PCF and they are "de facto" expressed officially by different orientation texts or lists for leadership elections at party congresses. Preparatory votes on orientation texts for PCF Congresses since 2003: At the XXXIV Congress in 2008, for the election of the national council, the majority's list won 67.73% from the congress' delegates against 16.38% for Marie-Pierre Vieu's "huiste" list backed by the "refondateurs", 10.26% for André Gerin's orthodox list and 5.64% for Nicolas Marchand's "novateur" list. Currently, the PCF retains some strength in suburban Paris, in the Nord section of the old coal mining area in the Nord-Pas-de-Calais, the industrial harbours of Le Havre and Dieppe, in some departments of central France, such as Allier and Cher (where a form of sharecropping existed, in addition to mining and small industrial-mining centres such as Commentry and Montceau-les-Mines), the industrial mining region of northern Meurthe-et-Moselle (Longwy) and in some cities of the south, such as the industrial areas of Marseille and nearby towns, as well as the working-class suburbs surrounding Paris (the "ceinture rouge"), Lyon, Saint-Étienne, Alès and Grenoble.
