STOCKHOLM — Sweden’s election has produced one of the closest results in modern history, leaving the country’s political future unresolved and placing concerns over Russian influence at the centre of a campaign already shaped by national security, NATO and a changing political landscape.
Preliminary results from Sunday’s parliamentary election projected the center-left opposition led by former Prime Minister Magdalena Andersson to win 175 seats, against 174 for Prime Minister Ulf Kristersson’s governing right-wing bloc. With overseas and remaining ballots still to be counted, the final outcome could still change.
The one-seat margin has placed extraordinary weight on an election that was already politically consequential. A victory for Kristersson’s bloc could bring the Sweden Democrats, which has supported the government from parliament since 2022, formally into government for the first time.
But in the campaign’s final stretch, another issue moved into the foreground: Russia.
Swedish investigative outlet Expo raised questions about alleged pro-Russian activity involving Polina Malaberg, a Sweden Democrats parliamentary staffer whose work placed her close to senior political figures and parliamentary committees. The allegations centered on previous statements, contacts and activities connected to Russia.
The case became particularly sensitive because Malaberg is the partner of Gustav Gellerbrant, a senior Sweden Democrats official who has played an important coordinating role between the party and Kristersson’s government.
Prime Minister Kristersson said Malaberg should lose her position if the allegations were substantiated.
There is, however, no publicly presented evidence that Malaberg worked for Russian intelligence, passed classified information to Moscow or participated in a Russian intelligence operation. The controversy should therefore be distinguished from documented Russian interference activity identified separately by Sweden’s security authorities.
Sweden Has Already Disrupted a Russian Influence Operation
That broader threat is not theoretical.
In August, Sweden’s Security Service, Säpo, announced that it had disrupted an intelligence operation planned and directed by Russia’s foreign intelligence service, the SVR.
The operation sought information about Swedish political decision-making that could be used in influence activities around polarizing issues, with the aim of undermining Swedish decision-making and discrediting Sweden, NATO and the European Union.
Säpo has also warned that Russian intelligence remains particularly focused on Sweden’s positions within NATO and the EU, its military capabilities and its support for Ukraine.
The warning carried particular weight ahead of Sweden’s first parliamentary election since joining NATO in 2024.
Sweden’s Election Security Moves to the Forefront
Swedish authorities had spent months preparing for precisely this type of threat.
In February, Kristersson brought together leaders of every party represented in parliament for a briefing with the Election Authority, Security Service and Psychological Defence Agency on protecting the election against malign information influence.
The government has cited both the deteriorating security environment and attempted interference elsewhere in Europe as reasons for strengthening Sweden’s election defenses.
New election-security legislation that entered into force in December 2025 also expanded the Election Authority’s responsibility for coordinating protection of the voting process.
Sweden’s electoral system is considered particularly resistant to direct manipulation because it is decentralized, votes are counted multiple times and counting is open to the public. Authorities have consequently focused heavily on another vulnerability: attempts to manipulate the information environment or undermine confidence in election results.
A Political System in Transition
The Russia controversy intersected with a broader transformation of Swedish politics.
The Sweden Democrats, a nationalist party with roots in Sweden’s far-right movement, emerged from political isolation to become a crucial parliamentary partner to Kristersson’s government following the 2022 election.
The party has since helped shape policies on immigration, crime and integration. This year, its potential entry into government became one of the campaign’s defining questions.
Despite the intensity of that domestic debate, Sweden’s broader geopolitical orientation is unlikely to shift dramatically regardless of which bloc ultimately forms the next government.
Support for NATO membership, assistance to Ukraine and close cooperation with European allies remains firmly embedded across much of Sweden’s political spectrum.
The New Front Line of European Elections
The significance of Sweden’s experience may therefore extend beyond whether Moscow succeeded in changing votes.
Modern influence campaigns often seek something more diffuse: amplifying existing divisions, damaging trust in institutions and making democratic societies less confident in their own political processes.
Sweden has explicitly identified foreign malign information influence as a threat and built an inter-agency system involving security, election, cyber and psychological-defense authorities to counter it.
There is currently no public evidence that Russian interference altered Sweden’s election result.
But the combination of a confirmed Russian intelligence operation, political controversy over Russia-linked activity and a parliamentary contest potentially decided by a single seat illustrates the increasingly complex security environment surrounding European elections.
For Sweden, the immediate question is who will govern.
The longer-term question is one facing democracies across Europe: how to protect not just ballots, but public confidence in the institutions and information systems surrounding them.
