Dyson launches Airblade hand-drying tap

Dyson - the British engineering group - has unveiled a device that combines a high-speed hand dryer with hot and cold water outlets.

The Airblade Tap builds on the firm's success with its existing standalone cold air hand driers, but is more expensive at £1,000.

The firm's founder Sir James Dyson said that the device offered long-term savings over hot-air dryers and towels.

The BBC's Mark Gregory visited Dyson's headquarters for a preview of the product, with Sir James Dyson.
