PARIS: French competition regulators are nearing the end of a two-year investigation into alleged price-fixing of household cleaning products by nine leading European and US firms, including Procter & Gamble,Colgate-Palmolive and Unilever.

Antitrust watchdog Conseil de la Concurrence has remained zip-lipped on details of the probe, save to say it was launched in 2006 after a tip-off by a whistleblower at one of the companies under investigation.

Commented PG& spokesman Robyn Schroeder: "We have been collaborating with the investigators and will continue to do so. To date, no formal request has been sent by the authorities to P&G following this investigation."

If found guilty, the companies could be fined up to 10% of their global sales.
