The Daily Telegraph looks at the IEA's latest research paper

The Institute of Economic Affairs, a think tank, in an in-depth report into Fair Trade said that the scheme “often better reflected the prejudices of western consumers than the needs of poor producers”.

The label, which was on nearly £1 billion of goods over the last 12 months, can be found on chocolate, coffee, tea, bananas and other food.

The scheme promises to pay producers a guaranteed price for their goods and a premium above the market price.
