German car giant Volkswagen may wait until the autumn to appoint a successor to former human resources chief Peter Hartz, who quit earlier this month amid a financial scandal, VW's chairman Bernd Pischetsrieder said in a newspaper interview Friday. "It could take until November," Pischetsrieder told local daily Braunschweiger Zeitung. "Internal processes must first be put in order," he said. Until a replacement can be found for Hartz, Pischetsrieder himself is taking responsibility for personnel affairs within VW. No names of possible successors had yet been discussed, he said. Hartz has vehemently denied any wrongdoing but he offered his resignation at the beginning of July as a bribery and corruption scandal engulfed Europe's biggest car maker.
