Danes are voting in an election with Prime Minister Mette Frederiksen's Social Democrats aiming for a third term. Frederiksen, 48, called the vote months earlier than expected, buoyed by popular support for her handling of US President Donald Trump's threat to annex Greenland, an autonomous Danish territory. Her Social Democrats have lost support since the 2022 elections and she is facing a strong challenge from two parties on the centre-right, including the Liberal Venstre party of Defence Minister Troels Lund Poulsen. Denmark is run by coalition governments and Tuesday's vote will decide whether power will stay with a left-wing bloc or move to the right.

Latest opinion polls give Frederiksen's Social Democrats the largest share of the vote, on more than 20%, well ahead of the Liberals and Green Left. Although the election is not being fought on the Greenland crisis, Frederiksen is gambling that the 'Trump bump' that boosted her poll numbers after her defiant stance on Greenland will be enough to secure a third term in a tightly contested race. However, despite leading in polls, the Social Democrats may face their weakest result in over a century. Key issues such as the economy and cost of living dominate the campaign trail, alongside concerns over agricultural practices affecting drinking water. With the centrist Moderates likely to play a crucial role in coalition building, the outcome remains uncertain.
