Sweden’s centre-left bloc has secured a narrow parliamentary majority in the 2026 general election, defeating the alliance led by outgoing Prime Minister Ulf Kristersson by just three seats. The result gives former prime minister Magdalena Andersson the first opportunity to form a government, but difficult negotiations between her allies could delay the process.
Kristersson has resigned, allowing the speaker of the Riksdag to begin formal discussions with party leaders. Sweden’s election result leaves the centre-left with control of the 349-seat parliament, although only around 50,000 votes separated the two main blocs nationwide.
Centre-left parties win three-seat majority
The winning alliance is led by Andersson and the Social Democrats. It also includes the Left Party, the Greens and the Centre Party. Together, the parties hold a three-seat majority over Kristersson’s right-wing alliance.
Andersson said voters had chosen “a new direction” for Sweden. Her next task is to secure a workable cabinet and a governing arrangement that can survive parliamentary votes.
The result does not mean that the centre-left government is automatically formed. Sweden’s parliamentary system requires negotiations between the parties before the speaker can propose a prime minister and the Riksdag can approve the government.
Coalition negotiations could prove difficult
The four parties that make up the centre-left bloc share an electoral victory but have significant policy differences. The Centre Party has said it will not support a government that gives cabinet positions to the Left Party, while the Left Party wants representation in the ministerial team.
That disagreement could become the central challenge for Andersson. She may need to find a compromise involving a minority government, a formal cooperation agreement or another arrangement that allows the coalition to pass budgets and key legislation.
Kristersson has said he will respect Andersson’s attempt to form a government and wished her success, despite the divisions within the incoming bloc. If Andersson cannot assemble a viable administration, Kristersson could still seek to form an alternative government.
Sweden’s government formation process
Coalition talks can take considerable time in Sweden. Government formation after the 2022 election took more than five weeks, while the process following the 2018 election lasted almost 20 weeks.
The speaker of parliament will now consult the party leaders and work towards identifying a candidate capable of winning enough support in the Riksdag. The election result therefore marks the beginning of a new political phase rather than the immediate start of a new administration.
Major parties lose support despite bloc victory
Although the centre-left bloc won overall, the Social Democrats recorded their weakest result in more than a century. The party lost eight seats but remained Sweden’s largest political force, receiving 28% of the vote.
The Social Democrats governed Sweden for much of the 20th century, but the result highlights the changing balance of Swedish politics and the difficulty of translating bloc-level success into strong support for an individual party.
The Sweden Democrats also suffered a setback. Their share of the vote fell to 17.5%, accompanied by the loss of 11 seats. It was the first time the party had lost support since entering the Riksdag in 2010.
The decline on both sides suggests that the election was shaped not only by competition between the two governing blocs, but also by voter movement within them. Smaller parties may now have greater influence over the composition and priorities of the next government.
Why the Swedish election matters beyond Sweden
Sweden is an important member of the European Union, and the formation of its next government could influence European politics in several areas, including economic policy, security, migration and climate measures.
A centre-left administration involving the Social Democrats, Greens, Centre Party and Left Party could produce different priorities from Kristersson’s outgoing right-wing government. However, the precise direction will depend on the coalition agreement and the compromises reached during the talks.
The result has already drawn international attention. Spain’s Prime Minister Pedro Sánchez welcomed the outcome, presenting it as a victory for social democracy and the welfare state.
For the EU, the immediate issue is not a new policy decision but political stability in one of its member states. Sweden’s position on European legislation and cooperation will become clearer once a government is formally appointed and its programme is published.
What happens next?
- The speaker of the Riksdag will consult party leaders.
- Magdalena Andersson will attempt to negotiate a governing arrangement.
- The parties must resolve their disagreement over cabinet representation and policy priorities.
- The Riksdag will consider the proposed prime minister and government.
- If Andersson cannot secure sufficient support, Ulf Kristersson may attempt to form an alternative administration.
Until those steps are completed, Sweden remains in a transitional political period. The centre-left has won the parliamentary contest, but the shape and durability of the next government are still uncertain.
Conclusion
Sweden’s election has delivered a narrow centre-left majority and ended Ulf Kristersson’s term as prime minister, but Magdalena Andersson still faces difficult coalition negotiations. The three-seat advantage gives her the first chance to govern, while disagreements between the Centre Party and Left Party could determine whether that victory becomes a stable administration. The next major development will be the speaker’s consultations and the formal attempt to build a government.
