premise: The rise and fall in the annual gross income of Britains biggest supermarkets is well documented. For this reason it came as no surprise to many when Tescos annual figures represented a loss this quarter. Official figures suggest that a price-cutting campaign by Britains biggest retailer failed to plug the losses, as Tesco made its fourth quarterly loss in a row. Commentators suggest that the fall in sales is a result of the current economic climate, with shoppers not only spending less on clothing and electronic items, but also on their weekly food shops. However, this view is controversial as smaller competitors, such as Sainsburys and Morrisons, continue to make a profit.
hypothesis: Competitors, such as Sainsburys and Morrisons continue to make a profit on clothing and electrical items.
