Mediapart is not Le Canard enchaîné.[1] Though Le Canard enchaîné is not available for free online. Their reporting also tanked Fillon's chances during the last French presidential election.
One can think of Le Canard enchaîné as the French version of Private Eye.
The original Mediapart story also references Le Canard enchaîné.[2]
