Charlotte Church sings This Bitter Earth outside Shell's London HQ in protest at plans to begin drilling in the Arctic. The Welsh singer told the crowds gathered under Hungerford bridge she wanted to make the company question what they are doing. The event was staged by Greenpeace, which has been putting on performances every day for the past month as Shell's vessels have been waiting to proceed through the Chukchi sea, north-west of Alaska
