Did you know that Nestle Kit Kat is Britain's biggest selling biscuit with about 1 billion sold each year?

Following a move by Cadbury's Dairy Milk which is the UK's best selling chocolate bar and which became Fairtrade certified in March 2009, Nestle Kit Kat becoming certified will mean that 6,000 farmers in West Africa will get a better price for their cocoa which in turn should impact on their livelihood for them and their families.

The biscuit, with the poplar tag line 'have a break have a Kit Kat' will be giving the farmers a break - or at least a chance of escaping from poverty as they will get a guaranteed minimum price plus a premium of more than £100 a tonne with the Fairtrade agreement.

What a great example of how western brands can do social good.
