Today sees the start of Livestock 2013 at the NEC in Birmingham. It's hailed as one of the largest events in the farming calendar. And it also sees the launch of the National Farmers Union's new strategy for the british dairy industry. At the moment imports of dairy products are worth 1.5 billion pounds more than the dairy goods the UK produces at home. The NFU wants farmers to get enough money for their milk so they can invest in their businesses and increase production, to narrow that trade gap. Also on today's programme, DEFRA Secretary Owen Paterson has just returned from a UK trade delegation in New York where he's been trying to drum up more export trade to the US. The UK already exports £1.8 billion worth of food and drink to America, making it the third largest export destination after Ireland and France. And Anna Hill explores why the UK is just one of three countries in the world which exports significant amounts of beans to North Africa. Presented by Anna Hill, Produced by Anna Varle.
