Slow sales of Vista PCs have made a £20m dent in the first-half results of Dixons Stores Group International (DSGI).

In a prepared statement, group chairman Sir John Collins said: "The reduction in laptop stocks that arose out of disappointing sales of Vista-related products and a changing sales mix have reduced gross margins by around 2 per cent in the computing division, impacting [DSGI's] profits by around £20m in the first half. "

Across DSGI, sales grew 5 per cent growth on the same period last year, driven by demand for flat-panel HDTVs, laptops, digital SLR cameras, games consoles and accessories.

Against that performance, the relatively poor performance of the computing division dragged down gross margin by 0.6 per cent across the group.
