Former Volkswagen CEO Winterkorn denies any wrongdoing at emissions inquiry

Former Volkswagen CEO Martin Winterkorn has denied early knowledge of the company's cheating on diesel emissions as he testified to a German parliamentary inquiry.

It was his first major public appearance since the 69-year-old resigned in September 2015, several days after news of Volkswagen's use of software to cheat on emissions emerged in the US, saying that he was not aware of any wrongdoing on his part.
