Ex-VW boss Matthias Müller in the diesel trial: Martin Winterkorn like a “heap of misery”. “The whole topic was foreign to me,” said the 70-year-old as a witness in the Braunschweig Higher Regional Court.

The scandal broke on September 18, 2015, when the US Environmental Protection Agency (EPA) reported manipulation of diesel car emissions tests. The plaintiff investors feel that Volkswagen informed them too late.
