The question is not to know if Le Monde and Libe are Left or centre left (if it was the case could you please provide precise criteria?), but to know if some of the media were channeling left-wing narratives. I claim it is the case, mentioning Le Monde, France Inter and Libé and I could also mention Le Nouvel Observateur, Marianne and many others.

Unless you think anything to the right of Olivier Besancenot does not belong to the Left...
