As Malmö receives the keys to this year's event, we look at how Copenhagen in Denmark could be the real economic winners - without having to pay for it. When the Swedish city last hosted the competition in 2013, officials estimated around a third of overnight stays were in the Danish capital. We speak to officials in both cities - just 30km apart and connected by the Øresund Bridge - to examine what fans can expect, and explore how other nations around the world get in on the action when a neighbouring country hosts a global event.Produced and presented by Daniel Rosney
