The price of coffee on commodities markets has reached its lowest levels in decades, partly as a result of oversupply - though the weak pound means this will make little difference to consumers.

Simon Bower, head of wholesaler Pollards, told the BBC: “Unfortunately at the same time as the coffee prices come down the pound has weakened. All coffee is traded in US dollars and the pound is very weak at the moment.

“So the cost of coffee delivered in the UK is about the same as it was two or three years ago.”
