LONDON (Reuters) - Britain and the European Union have a good chance of striking a deal on future relations, the British government’s Northern Ireland minister Brandon Lewis said on Sunday. The United Kingdom left the EU in January but the two sides are trying to clinch a deal that would govern nearly a trillion dollars in annual trade before a transition period of informal membership ends on Dec. 31. Talks resumed last week after Britain walked away in frustration at what it saw as the EU’s unwillingness to compromise on key issues. On Friday, Britain said there had been good progress since the restart.
