UK supermarket William Morrison has reported an 8.4% rise in like-for-like sales for the first 14 weeks of its financial year, compared to 7.6% growth in the first five weeks. Excluding petrol, sales growth was 12.5%, or 6.9% on a same-store basis. "These increases are the result of both higher average number of customers per store and a rise in transaction values," the north of England-based family firm was quoted by Reuters as saying.
