The chairman of the supervisory board of Siemens, Heinrich Pierer, has resigned amid ongoing investigations into allegations of bribery and corruption among Siemens executives and staff.

The Inquirer says that although Pierer is not involved in the investigations, he will resign because his duty lies to the firm and its 400 000 global employees.
Although Pierer is not involved in the investigations, he will stand down because he said his duty lies to the firm and its 400,000 worldwide employees.
"A personal responsibility in view of the current investigations was not the basis for my decisions," Pierer says in a statement. "Siemens is in a difficult situation due to the in-part apparent and in-part alleged misconduct of a number of managers and employees.
"The sole reason for my decision today is to serve the best interests of Siemens," Pierer says.
Michael Mirow is acting chairman until a new chairman is elected at the end of Siemens' financial year.
