Seven major British retailers, including Asda, Iceland Foods, Marks and Spencer, Ocado, Wm Morrison Supermarkets, Aldi, and the Co-op, are seeking damages from several Norwegian salmon farming companies and their UK subsidiaries. They claim that alleged price-fixing by these companies resulted in a combined loss of $850 million. These retailers, which represent over 44 percent of the UK grocery market, have made total estimated combined purchases of farmed Atlantic salmon of around £1.7 billion.
