We spend more on chocolate each year than investors spend on gold - but as Easter approaches, how much do we really know about where it comes from or how it is made?
Panorama reporter Paul Kenyon goes undercover as a cocoa trader in West Africa and discovers children as young as seven working long hours on cocoa farms, helping to make the chocolate we love so much. He buys a tonne of cocoa made with child labour, and sees how easy it is to sell it into the supply chain which leads to our high streets.
He also helps rescue a 12 year old boy - trafficked across borders - to pick cocoa as a modern-day slave and reunites him with his mother. For the first time, we meet the kids who harvest our cocoa but who have never tasted chocolate.
