Authorities investigate Florent Montaclair over award given to himself and others including Noam Chomsky

At a ceremony at the French national assembly attended by Nobel prize winners, former government ministers, MPs, decorated scientists and academics, all attention was on a previously unknown literature professor.

Florent Montaclair, then 46, a balding, bespectacled figure in an ill-fitting suit and rosé-coloured shirt, was receiving the 2016 Gold Medal of Philology - the study of linguistics – from an international society of the same name.
