Denmark is to hold a new referendum on whether to adopt the euro and also ditch its other opt-outs from the core aspects of European Union integration, the country’s newly re-elected prime minister announced on Thursday.

Anders Fogh Rasmussen, who won a historic third term in general elections earlier this month, said Denmark’s four opt-outs – from the single currency and areas of defence and security cooperation – had become increasingly burdensome and should be scrapped.
