Charlotte Church adds her voice to Arctic oil protest

Singer will perform outside Shell's headquarters in London to campaign against the company drilling for Arctic oil and to raise awareness of climate change

She's performed for the pope, the Queen and the former president of the United States, but next week Charlotte Church will turn her attention - and her voice - to the employees of the oil giant Shell.

On Wednesday the singer-songwriter and actor will sing a "heartbreaking" song alongside a requiem outside Shell headquarters in London, as its oil exploration vessels gear up to restart drilling for oil in the Arctic. She hopes it will highlight the oil firm's "nonsensical and exploitative" billion dollar venture under the ice cap and persuade its employees to blow the whistle on the company.
