The Oresund Bridge between Denmark and Sweden is perhaps one of the most potent symbols of the close ties between European countries. Three decades ago the two countries opted to go passport-free as part of the Europe-wide "Schengen" zone.
But much has changed since then.
Sweden and Denmark – for years regarded as two of the most liberal countries in the world and a model for left-leaning proponents of wealth distribution -- are reintroducing border checks in response to an influx of migrants into the European Union (EU). The move has been described as the beginning of the end, the writing on the wall and adds to the growing list of countries that have brought an end to passport-free roaming across their borders.
