On 10 April 2015 Ferdinand Piëch, chair of Volkswagen’s supervisory board, told Der Spiegel: Ich bin auf Distanz zu Winterkorn. I am keeping my distance from Winterkorn. Martin Winterkorn was the company’s chief executive. A week later, the presidium of the supervisory board called Winterkorn the best possible chief executive and proposed extending his contract. According to the news agency dpa, the other five members of the presidium all stood against Piëch. On 25 April Piëch resigned from all his posts at Volkswagen with immediate effect.
