Former Volkswagen boss Martin Winterkorn quits as head of holding company

Former Volkswagen CEO Martin Winterkorn is stepping down as head of a holding company that technically controls a majority in the German automaker, weeks after his resignation in the wake of the emissions-rigging scandal.

Porsche Automobile Holding SE, via which the Piech and Porsche families own more than 50% of Volkswagen, said in a brief statement today that it "reached an agreement with Prof Martin Winterkorn that he ceases his function as member and chairman of the executive board of Porsche SE by the end of October 31."

Winterkorn will be replaced as the holding company's CEO November 1 by Volkswagen's new supervisory board chairman, Hans Dieter Poetsch.

Winterkorn's departure as head of the holding company was expected after he quit last month as CEO of the automaker, a few days after news broke of the scandal over software built into diesel engines that disabled emissions controls except when they were being tested.

Winterkorn resigned as VW CEO on September 23, saying he was acting in the interests of the company "even though I am not aware of any wrongdoing on my part." He was succeeded in that job by former Porsche CEO Matthias Mueller.
