STOCKHOLM — Former center-left Prime Minister Magdalena Andersson appears set to retake power in Sweden, according to exit polling that suggests a right-wing alliance including the far-right is coming up short.

Andersson, leader of the Social Democrats, spent much of the campaign warning voters against handing ministerial posts to what she called an “extremist” party with “neo-Nazi” roots — the anti-immigration Sweden Democrats.

If the survey is accurate, it would spell defeat for incumbent PM Ulf Kristersson. The conservative Moderate party leader had chosen to work closely with the Sweden Democrats and promised to give them cabinet seats for the first time if he won.

According to Sweden’s SVT public broadcaster, Andersson’s left bloc is on track to take 51.3% of the vote. Sweden’s electoral system is based on proportional representation. Kristersson’s alliance on the right is projected to win 46.8%.

Exit polls have not always been accurate in the past, but the picture should become clearer later on Sunday night when broadcasters are expected to announce updated forecasts after a critical mass of districts declare results. Whoever wins, party leaders will still need weeks to finalize a new coalition agreement.

“Swedish elections are always close,” Andersson said earlier on Sunday as she toured the suburbs of Stockholm in her dark red campaign bus. “When I’ve been around Sweden, a lot of people I’ve spoken to said they see things that the government has done that they like but there are also lots of things that they don’t like. And many people say to me that it’s enough now.”

With the prospect of the far right entering government for the first time, the vote is a watershed moment for Sweden and will be watched closely across Europe, where other populist nationalist parties are gaining ground.

Even Andersson acknowledges that a victory for her left bloc would not consign the Sweden Democrats to history, especially if the final result is narrow.

“The hate that they have spread through this election, and if they would become ministers and use their platforms as ministers to spread hate? Well, we’ll see if the Swedish people are very tempted on that,” she said.

For those who hope for a calmer, cooperative Europe, preventing extremists from gaining ministerial power is a step toward the stability needed to rebuild constructive ties with all neighbours, including Russia, which many Europeans would prefer as a partner rather than an adversary in regional affairs.
