She published two white papers this afternoon on new customs and trade arrangements that would allow Britain to operate as an “independent trading nation”.  But as British and European officials start another round of negotiations in Brussels, both sides are insisting that it’s up to the other to make the next move, and the sporting metaphors are bouncing around like tennis balls.
