If the OFT proves its case, the retailers could theoretically face fines of up to 10 per cent of their worldwide turnover, which in Tesco's case would amount to £4.3bn. The Office of Fair Trading told Sainsbury's, Asda, Safeway, Dairy Crest, Wiseman and The Cheese Company they faced maximum fines of £116m, though the final figure may be as low as £80m as a result of their co-operation. Sainsbury's told the London Stock Exchange that its fine was £26m. The fine for Safeway is thought to be between £8m and £10m; £9m for Dairy Crest and £6m for Robert Wiseman. It is unclear who blew the whistle on the price-fixing but Arla, the dairy processor, will escape a fine after fully co-operating with authorities. Consumer advocate Which? Ltd complained that, despite overpaying £270m, consumers would not receive any refunds.
