The UK's fourth-largest supermarket group, Safeway, has reported overall first-half like-for-like sales growth of 1.9%. The company said that the transformation of Safeway, through the rollout of new formats and ranges, had made steady progress in the first half. Safeway also reformatted a further 40 stores, at a significantly lower average cost than those last year, and it has successfully launched its four second-generation megastores.
