Mette Frederiksen is the prime minister of Denmark and leader of the Social Democrats. She served as party leader for four years before becoming prime minister in 2019. She was 47 years old as of mid-2025, making her one of few social-democratic leaders left in office in Europe.
Frederiksen has been the architect of Denmark's shift from reliance on America's security umbrella to massive rearmament; defence spending should reach 3% of GDP in 2025. She is simultaneously raising the retirement age to 70, Europe's highest. She was once a leading candidate to be NATO's secretary-general.
After Donald Trump threatened to acquire Greenland by force in January 2026, Frederiksen warned that any such move would spell the end of NATO. She implored Trump to drop the threats, adding that they "should be taken seriously."
In November 2025 the Social Democrats lost control of Copenhagen for the first time in a century. On February 26th 2026 Frederiksen called a snap election for March 24th, capitalising on a surge of support after defying Donald Trump over Greenland. Her party recorded its worst electoral score in well over a century. On May 8th 2026 her initial bid to form a coalition government failed; her deputy, Troels Lund Poulsen, was asked by the king to try to form a centrist coalition instead. She is one of only three centre-left leaders heading EU national governments (alongside Pedro Sánchez of Spain and Robert Abela of Malta).
Frederiksen has adopted a hardline stance on immigration that borrows from populist parties on the right. She enthusiastically carried forward a law cracking down on "parallel societies"—estates housing many people with "non-Western backgrounds"—that can be razed or sold off if crime and unemployment remain too high. In 2021 it was proposed under her watch that asylum-seekers should be processed in Rwanda, a plan that fizzled. Denmark held the EU's rotating presidency in the second half of 2025, giving Frederiksen a platform to promote her migration approach to the rest of the bloc.
The best way to avoid responsibility is to say, "I've got responsibilities."
