Former Volkswagen CEO Martin Winterkorn goes on trial over diesel emissions cheating scandal allegations

Martin Winterkorn, the former CEO of Volkswagen, is facing trial in Braunschweig, Germany, on charges of fraud and market manipulation related to the "dieselgate" scandal. Prosecutors claim that Winterkorn was aware of the illegal software used to rig emissions levels in millions of vehicles worldwide before it was made public in 2015. Winterkorn has testified in civil proceedings that the allegations against him are incorrect, but the trial is ongoing. The charges against him include fraud over the use of "defeat devices" to manipulate emissions levels.
