In the first Democratic primary debate, both Hillary Clinton and Bernie Sanders spoke of their fondness for Denmark .

Sanders, in particular, suggested that the US could adopt a socialist system by emulating Scandinavia. “I think we should look to countries like Denmark, like Sweden and Norway, and learn from what they have accomplished for their working people,” said the US presidential candidate, who identifies himself as a “democratic socialist.”

But Danish prime minister Lars Løkke Rasmussen, speaking at Harvard’s Kennedy School of Government this week, says Sanders got more than a few things wrong.

“I know that some people in the US associate the Nordic model with some sort of socialism. Therefore I would like to make one thing clear. Denmark is far from a socialist planned economy. Denmark is a market economy.”
