British TV viewers will be able to do grocery shopping from their armchairs, thanks to a new agreement unveiled by supermarket group Sainsbury and cable TV firm NTL on Sunday.

The two have teamed up to launch the world's biggest TV grocery store, which will open its virtual doors on Monday.

NTL customers will be able to choose from more than 15,000 products on sale in Britain's second-biggest grocery chain, and have them delivered to their door.

" A television shopping service makes sense because so many people own a television," said Mr Robin Lassiter, director of home shopping at Sainsbury. - (Reuters)
