AN ADVENTURER from Poole has hit the road on a marathon journey to Timbuktu - in a lorry powered by chocolate.

John Grimshaw, 39, and fellow explorer Andy Pag boarded a ferry from Poole 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.

Both travellers are keen environmentalists aiming to raise awareness of the benefits of bio-diesel, which produces lower carbon emissions than fossil fuels and is made from renewable resources.
