Sweden goes to the polls on Sunday 13 September. Voters will elect all 349 members of the Riksdag, and on the same day choose 21 regional councils and 290 municipal councils. The date is not a political choice: Swedish general elections fall on the second Sunday of September on a fixed four-year cycle.

Voters do not elect a prime minister

This is the single most useful thing to understand about a Swedish election, and it is the thing most often lost in international coverage. There is no vote for prime minister. Voters elect the Riksdag; the Riksdag then decides who governs.

The mechanism is unusual. The Speaker consults the parties and proposes a candidate, and that candidate takes office unless an absolute majority of members votes against — 175 of 349. A prime minister therefore does not need a majority in favour. They need the absence of a majority opposed. That is why Swedish governments are frequently minority governments relying on outside support, and why the arithmetic after a Swedish election is often more complicated than the vote shares suggest.

Seats are allocated proportionally, and a party generally needs at least 4 per cent of the national vote to enter the Riksdag at all. That threshold does a great deal of work. A party polling near it can be worth a bloc’s entire majority, and small movements around 4 per cent matter far more than the same movement around 20 per cent.

Who is standing

Eight parties currently sit in the Riksdag, and Swedish politics has for some years organised itself into two loose camps rather than eight independent actors.

On one side is the sitting government: a centre-right coalition led by Ulf Kristersson of the Moderate Party, in office since 2022, governing with the parliamentary support of the Sweden Democrats under Jimmie Åkesson through the arrangement known as the Tidö Agreement. On the other is the opposition, led by the Social Democrats under Magdalena Andersson, who was briefly prime minister in 2021–2022, together with the parties to their left and the Greens.

For reference, the 2022 result gave the Social Democrats about 30 per cent and 107 seats, the Sweden Democrats about 20.5 per cent and 73 seats, and the Moderates about 19 per cent and 68 seats — with the right-wing bloc taking a narrow majority overall.

What the polls say, and what they do not

Published polling through the spring and summer has consistently put the left bloc ahead. Across major Swedish pollsters, the Red-Green side has been running in the low fifties and the governing parties in the mid forties, with the Social Democrats the largest single party by a wide margin and the Sweden Democrats and Moderates competing for second.

Three cautions apply, and they are not throat-clearing.

• A poll is a measurement with a margin of error, and bloc totals stack several parties’ errors on top of each other. A nine-point bloc lead is not nine points of certainty.
• Swedish campaigns move late. Party leaders’ debates and the final fortnight have historically shifted several points, and turnout in Sweden is high enough that late deciders are numerous.
• Seats, not percentages, form governments — and with the 4 per cent threshold in play, a bloc can gain votes and lose its majority if a small partner drops out of parliament.

The arguments of the campaign

Crime and gang violence have dominated Swedish political debate for several years and remain central. The government points to a programme of tougher sentencing and expanded police powers; opponents question how much of it has worked and argue that prevention has been underfunded. Both claims are, to a degree, testable, and both sides cite statistics selectively — which is a reason to read any single crime figure in this campaign alongside its baseline and its time period.

Immigration is the second axis, and it now runs through questions of citizenship as well as arrivals. The reform that introduced a civics test and a longer residence requirement took effect in June, and its first test was held only this month — see our report on Sweden’s first citizenship test. Labour migration rules, and the deportation of workers over administrative errors, have become a live argument inside the campaign, including from parties in the centre.

Then there is the ordinary business of an election: household costs, housing, healthcare waiting times, and what to do about welfare spending after several tight budgets. The opposition has signalled it would reverse parts of the government’s cuts. The government argues the fiscal room does not exist.

Foreign and security policy is, unusually, not much of a dividing line. Sweden joined NATO in 2024 after two centuries outside military alliances, and that decision commanded support across most of the political spectrum. The debate now is about defence spending and conscription rather than alignment.

The practical timetable

Everyone entitled to vote should receive a voting card by 26 August at the latest. Advance voting opens before election day at designated locations anywhere in the country, which in Sweden accounts for a large share of all votes cast. On 13 September polling stations are open from 8am to 8pm. A preliminary count follows that evening; the county administrative boards then conduct the final count, which is the one that decides seats.

Because advance votes and postal votes are counted on a different schedule from election-day votes, early figures on the night can move. In a close bloc contest, the picture at 21:00 is not necessarily the picture on Wednesday.
