UK eco-travellers set off in chocolate-powered lorry

Two British adventurers started their eco-journey to Timbuktu today in a lorry powered by chocolate.

Andy Pag and his co-driver John Grimshaw took the ferry from Dorset last night at the start of their 4,500-mile drive across the Sahara in a Ford Iveco Cargo lorry, powered by fuel that began life as chocolate.
