LONDON (AP) — One month after Britain made a New Year split from the European Union’s economic embrace, businesses that once traded freely are getting used to frustrating checks, delays and red tape. British meat exporters say shipments have rotted in trucks awaiting European health checks. Scottish fishermen have protested at Parliament over the catch they can no longer sell to the continent because of complex new paperwork. Manufacturers’ organization Make U.K. said Monday that 60% of manufacturing companies have experienced “significant disruption” since Jan. 1. The British government says the troubles are “teething problems,” but companies say they are causing serious pain.
