Andy Burnham is preparing to announce billions of pounds of EU trade deals in Brussels on 20 November, covering an agricultural agreement freeing up trade in goods like Scottish salmon and pet travel, access to the EU's emissions trading scheme, and a youth visa scheme for under-30s. He told the Economist a deal could add up to 0.4% to GDP, a boost he said "you cannot ignore", while elements face criticism that Britain is signing up to rules it left the EU to avoid.
