James Moore: Clean hands are needed to get VW back on the road after emissions scandal

The scandal engulfing Volkswagen has deepened, as they always do.

Authorities in Europe and South Korea formed an orderly queue behind the Americans with their own promises of investigations — and tough action if the carmaker is found to have sought to cheat their emissions tests and standards. Others will doubtless follow.

“Personnel action” is one of the measures now being considered by Volkswagen’s supervisory board as it gets to grips with an affair that — and it’s not an over-reaction to say this — threatens the future of one of Germany’s most iconic brands.

That might help. Having admitted to wrongdoing, the company needs to show it is willing to call responsible parties to account before regulators force it to.
