MPs backed Social Democratic Party leader Magdalena Andersson by a narrow margin in a new vote on Monday, November 29th.
She will attempt to lead a one-party government until an election in September next year.
Ms. Andersson had been elected as Sweden’s first female prime minister by a single vote in parliament last Wednesday. Hours later, she stood down as PM after her coalition collapsed.
But the 54-year-old economist’s plan for forming a new coalition government with the Green Party was thrown into disarray when her budget proposal failed to pass.
Instead, parliament voted for a budget drawn up by a group of opposition parties, including the far-right Sweden Democrats.
The Green Party said it would not accept a budget drafted by the far-right and walked away from the government, leading to its demise.
By convention, the prime minister in Sweden is expected to resign if a coalition party leaves the government.
In Monday’s vote in Sweden’s parliament, the Riksdag, 101 of its 349 members voted yes, 75 abstained and 173 voted no.
To be appointed prime minister under Sweden’s political system, a candidate only needs to avoid a majority voting against them.
At a news conference after the vote, Ms. Andersson said she was ready to “take Sweden forward” with a programme focused on welfare, climate change, and crime.
But without the support of other parties, Ms. Andersson will struggle to pass legislation in parliament, where the center-left Social Democrats hold 100 of 349 seats.
