Here's another post I made in that thread, which is better here, and it has a useful link in it.

As Susan said - there's no question about there being a system of child (and other) slavery on some of the cocoa plantations, and children being ferried around between various places in West Africa.

The question of whether they are going to be abe to pin anything on the people running this particular ship on this particular occasion is a very secondary matter.

The crucial quote is that one from the Benin minister: "I don't deny that Benin is part of the traffic in children".

I was pleased to see that Cadbury, the chocolate people, have called for effective action against slavery in the cocoa and chocolate plantations etc. Cynically one might say they are a bit worried about possible boycotts, and they want to make it clear that in this respect their company has clean hands. But it's a good practical development, which could achieve something.
