Sweden Steps Up Election Defenses Against AI-Driven Foreign Influence

Sweden is strengthening efforts to detect foreign information influence and coordinated attempts to manipulate political debate ahead of its general election. Authorities are focusing on how artificial intelligence and social media are changing the creation, distribution and amplification of political messages.

The government said greater resilience is needed because of the current security environment, rapid technological developments and lessons from elections elsewhere in Europe.

AI Network Shows How Influence Tactics Are Evolving

The Swedish Psychological Defence Agency last week reported a partly AI-powered network of about 1,200 fake accounts on X known as Holiday. The network generated more than 50,000 posts, comments and shares during 2025 and 2026 and was used for malign influence targeting Sweden and other countries.

Sweden’s central bank first identified the accounts after employees took part in an agency exercise, and X later removed the network. Holiday has not been directly linked to this year’s election, but authorities released the findings ahead of the vote to highlight emerging tactics.

TikTok And AI Change How Voters Get Information

One in 10 Swedes uses AI services to ask questions about politics or social issues, according to an April report from Sweden’s Internet Foundation. Among first-time voters, the share rises to one in four.

Recommendation systems can amplify sensational or emotionally charged content because it generates stronger engagement. Generative AI also allows networks to produce large volumes of material across multiple accounts at relatively low cost.

In February, Swedish public radio identified four TikTok accounts featuring AI-generated young women that promoted far-right and anti-immigration messages. The broadcaster found indications that the accounts were operated by the same actor.

Authorities Monitor Rising Online Activity

A Swedish Psychological Defence Agency poll found that 64% of adults believe foreign attempts to influence Sweden this year are very or quite likely. Meanwhile, the Swedish Defence Research Agency said election-related posts increased from about 1,000 a day to almost 2,400 shortly before early voting began.

Researchers have detected coordinated posting, identical content and fake accounts, but said the scale remains limited. So far, they have not attributed the activity to an organized foreign campaign.

Migration Remains A Key Disinformation Target

Migration-related narratives remain a particular focus because they have featured prominently in Russian disinformation efforts. Researchers have monitored claims that Sweden is being “Islamified,” that migrants were brought in to support left-wing parties and that electoral fraud is taking place.

“When we look at the topics that Russia has been pushing before, this is outgrowing every other topic, even support for Ukraine,” said Ola Svenonius, a senior researcher at the Swedish Defence Research Agency.

Despite these narratives, Sweden is not currently considered a priority target for Russian information influence by the Swedish Psychological Defence Agency. Svenonius said Moscow may instead focus on other elections, including German state contests.

Sweden Builds On Lessons From Earlier Elections

Authorities say Sweden is now better prepared to identify suspicious activity than during previous election cycles. Svenonius, who has monitored the country’s election information environment since 2018, said institutional awareness has also improved.

“We should be concerned,” he said. “We shouldn’t be panicked, but concerned for sure.”

Europe’s Deadly Summer Heat Exposed The Cost Of A Warming Continent

Europe experienced its deadliest summer for heat-related deaths on record in 2026, with an estimated 24,400 excess deaths linked to extreme temperatures across 30 countries. Researchers estimate that human-induced climate change was responsible for around 32,000 of the deaths attributed to heat in the study’s broader analysis, accounting for 65% of the total.

The findings highlight the growing public-health consequences of global warming, largely driven by fossil fuel use, as extreme heat becomes more frequent and severe.

A Summer Of Dangerous Heat

Between June and August, heatwaves pushed temperatures in Western Europe to an average of 2.9°C above the 1991–2020 norm, with some days reaching 12°C above average. Nearly a third of estimated heat-related deaths occurred during a particularly intense heatwave between 17 June and 1 July.

“These numbers are a stark reminder that our hotter, more extreme summers are having an increasingly severe impact on public health,” said Dr Clair Barnes, a researcher at Imperial College London and co-author of the study.

The estimated toll exceeded previous peaks of around 29,000 deaths in summer 2022 and 28,000 in 2003 across the region studied.

How Researchers Estimated The Toll

Researchers modelled the relationship between temperature and mortality across 854 urban areas in the EU, UK, Norway and Switzerland, covering around 40% of the population in the 30 countries studied.

The analysis incorporated temperature records, age, socioeconomic conditions, environmental factors and access to healthcare. By comparing actual temperatures with those expected without human-induced warming, the team estimated the additional deaths attributable to climate change.

Final official mortality figures for summer 2026 are not yet available in many countries, and heat-related deaths are often underreported because their effects can be difficult to identify directly.

Older People Face The Greatest Risk

People aged 85 and over accounted for roughly half of the estimated deaths. However, the impact extended across age groups, with around 800 excess deaths among adults aged 20–44 and approximately 6,000 among people under 65.

Southern Europe experienced the highest mortality burden, reflecting hotter temperatures and other vulnerabilities, including air pollution, limited green space and unequal access to healthcare and heat-alert systems.

Italy, France And Spain Record Highest Toll

Italy recorded an estimated 13,303 heat-related excess deaths, followed by France with 7,268 and Spain with 6,824. Germany recorded around 6,340, while the UK saw an estimated 4,354 deaths.

In the UK, the heat also placed significant pressure on healthcare services. Andrew Hartle, Professor of Practice of Anaesthesia at Imperial College Healthcare, said demand during the summer resembled that of a severe winter virus season.

Cities Urged To Strengthen Heat Protection

Researchers say cities can reduce the risks through climate shelters, external shading and building retrofits, alongside measures to help residents avoid exposure during the hottest hours. Checking on vulnerable people, staying hydrated and following heat alerts are also important.

The researchers stress that adaptation must go hand in hand with reducing fossil fuel use to limit further warming. The findings underline that extreme heat is already a major public-health threat across Europe, with thousands of lives at risk each summer.
