Some of the world’s biggest consumer goods companies have become targets for the Office of Fair Trading’s latest probe into alleged price-fixing between Britain’s biggest supermarkets and their suppliers.

Procter & Gamble, the leading consumer goods company worldwide, confirmed on Sunday that it was visited last Thursday by the competition watchdog, which also visited the headquarters of Tesco, Asda, J Sainsbury and Wm Morrison to request data about prices of groceries, health and beauty products and detergents.
