Greenpeace has launched a campaign against supermarket Waitrose in the run up to Christmas, following the food retailer's partnership with energy company Shell, which is planning to drill for oil in the Arctic.

The charity has released a spoof of the Waitrose Christmas TV advert, featuring chefs Delia Smith and Heston Blumenthal, and campaigners are calling on the supermarket to reconsider plans to open shops in Shell petrol stations.
