Farmers across the country fear they are facing another mapping fiasco. The Rural Payments Agency is in the process of issuing new maps, which are used as part of the calculation as to how much subsidy - the single farm payment - each farmer gets. Last time this happened, in 2005, problems with the maps led to massive delays in payments. This time, just 10 per cent of the maps have been issued, but hundreds of farmers say there are serious mistakes. Charlotte Smith talks to farmers about their concerns and asks the Rural Payments Agency what they are doing to find a solution.
