FRANKFURT -- The steering committee of Volkswagen's supervisory board will meet on Wednesday to discuss personnel chief Peter Hartz's offer to resign over a widening bribery scandal at the carmaker, the German state of Lower Saxony, a key shareholder, said on Monday.
Hartz on Friday offered to step down over the scandal, but the board must formally accept his resignation.
Group Chairman Ferdinand Piech, Lower Saxony state Premier Christian Wulff, IG Metall union chief Juergen Peters and new works council head Bernd Osterloh will attend, as will Chief Executive Bernd Pischetsrieder, a government spokesman said.
At Volkswagen's request, German prosecutors have opened an investigation into possible fraud and breach of trust by two former personnel managers to see if they improperly diverted company funds.
Volkswagen has also hired KPMG to perform an independent audit.
Hartz tendered his resignation to take responsibility for irregularities by employees, but he is not under investigation by prosecutors in Brunswick.
The head of the company's powerful works council, Klaus Volkert, also resigned, acknowledging that he was a business partner of the two suspects but saying he did not enrich himself at the company's expense.
The company and its works council have rejected accusations in the media that Volkswagen provided improper inducements to senior labor leaders in return for their support on key issues.
