Yorke in trade protest

Radiohead star Thom Yorke will join thousands of campaigners urging the British government to stamp out poverty caused by corruption in international trade.

The outspoken Paranoid Android singer will team up with fellow stars from the stage, screen and music industry outside London's political headquarters in Westminster to raise awareness of the Trade Justice Movement.

And Yorke is promising skeptics his involvement on April 15 will not be a fleeting, token gesture - he's prepared to devote a day and a night to the cause.

He says: "It's an overnight 'happening' - and it's happening at the same time as many events all around the world. I'm going with a sleeping bag and a paint brush and maybe even a guitar if I can get it in the suitcase."
