AMBER has always been something of a confusing stop-go colour. And now the UK Government is finding this out for itself as many Britons, desperate for a holiday following more than a year of Covid restrictions, are not quite sure whether it is safe to venture overseas or not thanks to mixed messaging from ministers. Boris Johnson might have thought his green-amber-red traffic-style system for travelling abroad was pretty straightforward. But, it seems, it is open to interpretation, including among his own ministerial colleagues. Earlier this week, George Eustice, the UK Government’s Environment Secretary, said people could go to countries listed as amber if they wanted to visit family or friends so long as they observed quarantine rules on their return.
