Yes, the French Interior Ministry's labels are a complete joke. For an imperfect, but still much better tally, you can have a look at the newspapers' websites, or to sites like [link]. Or hell, even the French Wikipedia.
Thanks.
One question to French people or those who knows:
Parties marked as "DIV"/Divers on most of the maps with results are mainly regionalist (there are some in Alsace, Corsica etc.) parties or also some centre parties and non-partisan candidates? And that "Divers droite" and "Divers gauche/PRG" are just nonsense, can't they show names of that parties? Even on the official webpage with results (some ministry) there was such division. Strange.
There is a bunch of non-partisan candidates among the Divers. Regarding the "divers gauche" and "divers droite", if the candidates register themselves as "right" or "left" instead of "UMP" or "PS"(there are many possible reasons for that), I am not sure it's the role of the election officials to impose them a label.
I am not sure if I understood all: candidates register themselves with such labels during candidates official registration? Weird. But thank you for the answer.
