Denmark's Social Democratic Party won the most votes in parliamentary elections but failed to secure a majority, leaving Prime Minister Mette Frederiksen facing complex coalition negotiations to remain in power.

The Social Democrats, which have governed Denmark since 2019, posted their weakest electoral performance in over a century, with results dating back to 1903. Despite winning the largest share of votes, the party fell short of the parliamentary majority needed to govern alone.

The election results create an uncertain political landscape, with Frederiksen's future as prime minister now dependent on her ability to forge agreements with other parties. The indecisive outcome means Denmark could face an extended period of coalition talks before a new government is formed.

Frederiksen will need to navigate negotiations with potential coalition partners to secure the support necessary to continue leading the country. The talks are expected to be challenging given the fragmented nature of the results and the Social Democrats' historically poor showing.

The election outcome reflects broader political trends across Europe, where established parties have faced increasing pressure from voters seeking change. Denmark's parliamentary system requires parties to work together when no single party achieves an outright majority.
