Morrisons is now selling one basic for a third more than competitors. Our weekly comparison of basics like milk and bread, which has been keeping track of the costs of the same eight products at the six main supermarkets since March, showed how the retailer had quickly moved from being the cheapest to the most expensive in a matter of weeks.
