The European Union is at a critical moment in its history, with Britain preparing to vote on whether to leave. In the third of a three-part series, the BBC’s Europe correspondent Chris Morris examines the multiple crises facing the EU. The economic crisis in the Eurozone is still not solved and an influx of refugees and migrants is threatening the future of Europe’s open internal borders. On top of this now comes the possibility of ‘Brexit’. Chris speaks to politicians and people across Europe and asks whether the EU will survive.
