Unlikely to actually be in a state prison, as it’s a short one, but still…
It’s basically revenge of the ENArque.
He was not ENArque and mightily pissed off the ENArque and showed their serial incompetence. So he had to be destroyed.
This trial was a footnote to the Affaire Bettencourt. Just another business as usual in French politics that was turned into a trawling exercise by his political enemies. The timing has more to do with next years elections than anything else. It will be interesting to see how the appeals go.
On a 1 to 10 scale of historical French political scandals maybe rates a 2 out of 10.
