The UK government has decided to keep ePassport gates open at ports and airports despite plans for a 14-day quarantine on all arrivals.Lucy Moreton from the IS union, which represents 4,000 border force officers, said ISU was pleased that the government has decided to keep these open.Customs officers will be required to check "as many people as possible" not everyone, so the flow of passengers and traffic at the border isn't compromisedMoreton also told the BBC's Today programme the quarantine system was almost impossible to enforce as it relied on the goodwill of travellers to follow complex rules that border staff had been given little time to understand."The staff are really angry that this does appear to be very shambolic and they don't want to be blamed for that," she said.British Airways, easyJet and Ryanair have threatened legal action against the measures and sent a pre-action letter to the government at the end of last week
