The Government has begun negotiating a Free Trade Agreement with Mexico, hoping to build on the deal inherited from the EU. We hear from a cheese producer looking to expand into this new market. Meanwhile, the UK Government has also signed a document called a Memorandum of Understanding with the US State of Indiana. But what will it mean for British farmers? And is vertical farming the future of food production? We visit a new facility being built just outside Norwich where they plan to grow 300 thousand bags of salad each week on a site of just four acres.
