Mette Frederiksen, Denmark’s Anti-Anti-Immigration Leader

In June she became the youngest person to lead a Danish government, then two months later drew President Trump’s ire by saying Greenland wasn’t for sale.

The Social Democrat, 42, won election after pulling off what few left-leaning political leaders in Europe have managed: neutralizing anti-immigrant nationalism. She acknowledged that curbs on immigration are needed in a country where everyone has access to free health care and education, but she did so without resorting to xenophobic rhetoric. At the same time, Frederiksen, the down-to-earth daughter of a trade unionist and a day-care worker from the northern city of Aalborg, pledged to protect low-skilled workers with laws that ensure their pay and job security won’t erode. In changing the tone of the debate, she may have established a model to reinvigorate the Left across Europe.
