And why would Lagarde neglect several hundred million Euro in favor of someone else?

Lagarde allowed a different between Mr Tapis and the state to go to arbitration where a panel of three judges awarded the several millions - not her. This choice was found to be negligent by the CJR, a court composed mostly of politicians, after the pay out was invalided by the French justice system 8 years later. Lagarde was found guilty of pushing for arbitration as a minister when she shouldn’t have.

To quote the linked article: “The verdict came as a surprise as even the public prosecutor had admitted the evidence against Lagarde was “weak” during a five-day trial last week.”

This has absolutely nothing in common with what’s happening to Marine Lepen. Dozens of emails and messages prove that she presided over a setup designed to embezzle millions for the EU while being fully aware this was illegal.
