Sainsbury's and Next to post rise in sales All of Sainsbury's beef is from the UK and Ireland, and the company has been conducting DNA tests on food for a decade. Philip Dorgan, at Panmure Gordon, has forecast that Sainsbury's will post like-for-like sales growth of up to 1pc in its trading update for the fourth quarter. Although this will be down on the 2.6pc sales growth last year, it is in line with the 0.9pc in the third quarter. Mr Dorgan said: "Many commentators will focus on the launch of Tesco's Price Promise, which sees Sainsbury's Brand Match and raises it by including own label. We think that this is all very interesting, but we are more concerned with the bigger picture. In common with its peers, Sainsbury's is finding it difficult to grow profits, despite substantial capital expenditure. Next, meanwhile, is expected to post a 4pc increase in annual sales on Thursday to £3.58bn, with pre-tax profits up 7pc to £618.4m. Lord Wolfson is likely to comment that currency movements and rising cotton prices could put more pressure on Next this year and, as a Conservative peer, he will also be asked about George Osborne's Budget. Retailers have called on the Chancellor to rethink business rates, with high street businesses facing a £175m inflation-linked increase in April. The British Property Federation has warned the Chancellor that business rates on empty property is draining more than £1.1bn a year from businesses.
