Social Democratic leader Magdalena Andersson has proposed forming a Swedish government with the Centre Party and the Greens, relying on “close cooperation” with the Left Party from outside the cabinet. She announced the plan at a press conference in the Riksdag on Sunday, Nov. 8, nearly two months after the Sept. 13 election left no bloc with a clear majority. The Left Party quickly signaled that the arrangement is not enough, putting Sweden government formation back into doubt.

Left Party group leader Ida Gabrielsson told SVT’s Agenda program that her party would vote against Andersson as prime minister unless it receives ministerial posts, citing a decision by the party congress, Sveriges Radio reported.

The arithmetic

The election gave the Social Democrats 99 seats, the Moderates 70, the Sweden Democrats 62, the Left Party 30, the Centre Party 25, the Christian Democrats 22, the Greens 22 and the Liberals 19, according to the Riksdag.

By The Boston Report’s count, Andersson’s proposed government would hold 146 seats. Adding the Left Party brings that to 176, just above the 175 needed for a majority. The four parties behind the outgoing Tidö agreement, the Moderates, Sweden Democrats, Christian Democrats and Liberals, hold 173. Under Sweden’s system, a prime ministerial candidate is approved unless a majority of 175 votes against, so the Left Party’s 30 votes can decide the outcome.

The Centre Party’s deadline

The Centre Party, now led by Elisabeth Thand Ringqvist, is the swing player. It has asked both Andersson and Moderate leader Ulf Kristersson to present their government proposals by Friday, Nov. 13, NordiskPost reported. On Nov. 6, the Sweden Democrats dropped their demand for cabinet seats, a move that makes a Kristersson-led government easier for the Liberals and possibly others to accept.

Andersson has also kept a fallback in view: a cross-bloc government of the Social Democrats and the Moderates, according to NordiskPost. That would command a majority on its own but would require the two largest rivals in Swedish politics to share power.

Why the Left Party matters

The Centre Party has long refused to give the Left Party direct influence over government policy, which is why Andersson’s plan keeps it outside the cabinet. The Left Party, for its part, has said it will not again back a Social Democratic prime minister without a seat at the table. Squaring those positions is the central problem for Andersson’s bid, and the Social Democrats’ own statement describes the Left Party role as close cooperation rather than membership.

The election itself was close. Kristersson’s Moderate-led government, in office since 2022 with the support of the Sweden Democrats under the Tidö agreement, lost its majority by two seats, while the Social Democrats remained by far the largest party. That outcome left the Centre Party and the Left Party, two parties that have refused to work closely with each other, holding the balance between the blocs.

What happens next

The rules also set a clock. Under the Instrument of Government, if the Riksdag rejects the Speaker’s proposed prime minister four times, an extraordinary election must be held within three months. No party has said it wants a new election, which gives every side a reason to settle, but it also lets smaller parties test how far the larger ones will bend before the fourth vote.

After Friday’s deadline, the Centre Party is expected to say which candidate it will support, and the Speaker can then put a name to a vote. If the Left Party holds to its position, Andersson would either need to offer it posts and risk losing the Centre Party, or turn to the Moderates. If Kristersson secures the Centre Party’s backing instead, the Tidö parties could return to power with a narrow margin.
