Volkswagen CEO Matthias Mueller has resigned following the company’s emissions scandal.
Mueller, who was named head of Volkswagen in November, resigned Friday, the company said in a statement.
The company said Mueller was relieved of his duties and “sincerely apologizes to Volkswagen owners, employees and stakeholders.”
Mueller was the subject of an internal investigation by the federal government over the emissions scandal at the German automaker.
Volkswagen had admitted that the diesel vehicles that are used in the U.S. had a defect that allowed the vehicles to spew emissions into the atmosphere, causing them to be more polluting than other vehicles.
The scandal led to the resignations of head of Audi AG, Oliver Blume, and chief executive of Volkswagen’s parent company.
The automaker also said Mueller will take on the role of CEO of the European Union’s chief trade mission, which is in charge of negotiating trade deals with the bloc.
The EU is currently negotiating with Canada on a new carbon-trading agreement.
