The Nordic Prime Ministers are a great bunch, aren’t they? They're the kind of people you'd probably be happy to hang out in the pub with.

This week, Bjarni Benediktsson of Iceland, Erna Solberg of Norweay, Juha Sipilä from Finland, Danish PM Lars Løkke Rasmussen and the Swedish leader Stefan Löfven all decided to troll their US counterpart by posing in a similar way to that photo...

They were together to promote the Nordic Solutions to Global Challenges initiative, a pooling of Nordic resources to help drive progress toward the UN 2030 Agenda Sustainable Development Goals.

Sustainable development is, of course, a superb goal for any country to strive for - but it's just extra special that the Nordic PMs decided to throw a little shade in there too.
