Computer-maker Dell has seen its quarterly profit fall by 47% after it was hit by falling sales to both consumers and large companies.

The US group made a net profit of $475m (£300m) in July to September, compared with $893m a year earlier.

Dell’s consumer revenues fell 23% to $2.5bn, while those from sales to big corporations declined by 8% to $4.2bn.

The company, the world’s third-largest maker of personal computers, saw overall revenues dip 11%.

Despite the poor results, Dell said it was more confident about the October to December period, which includes Christmas sales.

It expects group-wide revenues to rise by as much as 5% in the last three months of the year, despite the continuing “challenging” global economic environment.
