Sweden is gearing up for its parliamentary election on 13 September amid warnings that Russian‑linked troll farms and disinformation networks remain active, even if the vote is not a strategic priority for Moscow.

The Swedish Election Authority, together with the national cyber‑security agencies, has stepped up cooperation to protect the electronic voting infrastructure. Anna Nyqvist, chief executive of the Election Authority, told Radio Sweden that all bodies dealing with cyber threats are now working closely with the authority to safeguard the IT system that underpins the ballot.

Official assessment of the threat

Both the Swedish Security Service (SÄPO) and the Agency for Psychological Defence have concluded that the upcoming election does not sit high on Russia's agenda. Their statements echo the findings of the 2025 annual assessment released by the Military Intelligence and Security Service (MUST), which noted that Russian hybrid tactics are being directed primarily at countries where Moscow perceives a larger strategic payoff.

"Sweden is not seen as a high‑level priority for Russian information influence," said Patrik Oksanen, a senior analyst at the foreign‑policy think‑tank Frivärld. He added that Russia is preoccupied with other fronts and that the cost of mounting a large‑scale campaign in Sweden would outweigh any potential gains.

Oksanen's view is shared by Ola Svenonius of the Swedish Defence Research Agency, who explained that Swedish authorities estimate Moscow's main aim will be to maintain a background of uncertainty rather than to swing the election outcome. "The cost would be too high with regard to the rewards," he told reporters.

Why the election still matters

Even if the Kremlin does not allocate substantial resources to sway the vote, the Swedish government stresses that the election occurs in a "serious security situation" marked by "great uncertainty". The concern is not a single, spectacular hack but a slower, cumulative effort to erode public confidence in democratic institutions.

"If we are talking about broader Russian influence efforts, the aim is to take down trust in society, to undermine trust in the media, politicians, authorities," Oksanen explained. This strategy mirrors the pattern observed across Europe, where Russian actors amplify existing grievances and push polarising narratives through social media platforms.

In August, the public broadcaster SVT reported that a pro‑Russian troll network, operating mainly on X (formerly Twitter), had circulated fabricated videos and false claims of electoral fraud, including accusations aimed at Prime Minister Ulf Kristersson. The operation was linked to the broader influence campaign known as "Matryoshka", which has previously targeted elections in Germany and other EU states.

Last month, Swedish officials disclosed a separate Russian intelligence operation that involved the recruitment of an agent from a foreign embassy in Stockholm. While the case was not directly tied to the September vote, it underscored a pattern of long‑term, strategic activity aimed at weakening Western cohesion.

Broader hybrid pressure on NATO members

MUST's chief, Thomas Nilsson, warned that Russia is conducting "advanced hybrid warfare" against NATO countries, including Sweden. He said Moscow seeks to make allies feel insecure, split them internally and ultimately diminish support for Ukraine.

The Gdańsk declaration of June, signed by Sweden and other eastern‑flank nations, labelled Russia and its proxies as the "most significant, direct, and long‑term threat". The document cites persistent hybrid and foreign‑information‑manipulation campaigns designed to undermine democratic values and the European response to the war in Ukraine.

Sweden's proportional representation system further dilutes the impact of any single‑issue campaign. Unlike first‑past‑the‑post systems where a swing in a few key districts can decide government formation, Sweden's multi‑party landscape means that even a well‑orchestrated disinformation push would struggle to translate into decisive electoral change.

Moreover, there is a broad parliamentary consensus on supporting Ukraine. Parties across the spectrum, from the left‑wing Green Party to the right‑wing Sweden Democrats, have affirmed continued aid to Kyiv. "The soil is not very fertile for splitting Swedish politics on the issue of Ukraine," Oksanen observed, noting that Moscow's usual lever, exploiting divisions over the war, finds little purchase in Stockholm.

What the security upgrades entail

In response to the identified risks, the Election Authority has introduced several technical safeguards. These include enhanced encryption of vote‑transmission channels, real‑time monitoring of network traffic for anomalous activity, and a rapid‑response team that can isolate and remediate any breach.

Cyber‑security agencies are also conducting open‑source intelligence sweeps to identify coordinated inauthentic behaviour on social platforms. When suspicious accounts are flagged, they are reported to platform operators for removal, and the content is logged for further analysis.

Union representatives have welcomed the heightened vigilance, arguing that a secure election is essential for maintaining public trust in democratic processes. "Workers and ordinary citizens need to know that their vote cannot be tampered with or distorted by foreign actors," said Maria Andersson, a spokesperson for the Swedish Confederation of Professional Employees (TCO).

Business groups, while supportive of robust security, caution against measures that could impede legitimate political expression. The Swedish Chamber of Commerce urged authorities to balance protective steps with the need to preserve an open digital public sphere.

Looking ahead

As the election draws near, Swedish officials say they will continue to monitor the information environment closely. The focus will be on detecting coordinated campaigns that aim to spread false narratives about voting procedures, candidate integrity or the legitimacy of the results.

"We are not complacent because the threat is deemed lower priority," Svenonius stressed. "Our resilience measures are designed to ensure that even a modest attempt does not gain traction."

European observers note that Sweden's approach could serve as a model for other EU states facing similar low‑level but persistent interference. By integrating cyber‑defence, psychological operations analysis and transparent communication, the country aims to safeguard the integrity of its democratic exercise without stifling legitimate debate.

In the weeks to come, the real test will be whether these preparations can keep the election free from the subtle, long‑term erosion of trust that Russia has honed across the continent.
