Swedish parliament for the second time in less than a week has elected Social Democrat Magdalena Andersson as new prime minister.
The country's first female leader now must navigate a fragmented and fraught political landscape.
The former finance minister won a similar vote last week, but resigned hours later after a junior coalition partner abandoned the government over a lost budget vote.
Ms Andersson will now form a minority government consisting only of her own party.
The Social Democrats hold 100 seats in the 349-seat parliament and will have to rely on support from several other parties to implement policy. Not since 1979 has a government commanded so little direct support in parliament.
Complicating the picture, Ms Andersson will have to govern on a budget in part formulated by three opposition parties, including the anti-immigration Sweden Democrats, whose gains over the past decade lie at heart of Sweden's political turmoil.
Her tenuous hold on power is due to a deadlocked parliament where neither the centre-left nor centre-right can form a majority on their own.
An election due in September next year may not bring any further clarity as polls show little change in the overall political balance.
'Bulldozer' Andersson: Sweden's short-lived first woman
Last Wednesday, politicians elected Ms Andersson as the country's first woman prime minister but she resigned just hours later - before she even had a chance to formally take office - after the Green Party quit her coalition government.
The parliamentary turbulence was unprecedented in politically stable Sweden, where the Social Democrats have dominated for almost a century.
The tumult began when Ms Andersson secured a last-minute deal with the Left Party to raise pensions in exchange for its crucial backing to get her elected as prime minister.
But that agreement did not sit well with the small Centre Party, which withdrew its support for Ms Andersson's budget due to the concessions made to the Left.
That left Ms Andersson's budget with insufficient votes to pass in parliament.
Politicians instead adopted an alternative budget presented by the opposition conservative Moderates, Christian Democrats and far-right Sweden Democrats.
Ms Andersson grudgingly said she would still be able to govern with that budget, but the Green Party said it could not accept a budget drafted by the far-right and quit the government.
That meant Ms Andersson had to resign, as the basis on which she was appointed no longer existed.
While some experts say the Social Democrats will now have an easier time as the sole party in power without having to make concessions to a coalition partner, others predict a bumpy road ahead.
Ms Andersson's weak minority means she will have to seek support for her policies on both the left and the right.
Her most obvious cooperation partners are the Greens, the Centre and Left parties.
But she is also expected to court the right on issues blocked by the Greens during their time in government, including the expansion of Stockholms' Arlanda airport and a final depository for nuclear fuel waste.
Ms Andersson has also singled out crime and immigration - key voter concerns - among her top priorities, issues where the Social Democrats are closer ideologically to the centre-right.
The opposition has, however, been quick to point out that the right has the strongest constellation in parliament, and would likely be able to pass many of its policies without the Social Democrats.
The Moderates, Christian Democrats and Sweden Democrats are united on most issues and together control 154 seats in parliament, while the four parties on the left are more splintered.
"The Social Democrats will have to accept that it is parliament that decides and government obeys," Moderates leader Ulf Kristersson warned.
An economist who has served as finance minister for the past seven years, Ms Andersson took over as leader of the Social Democrats on 4 November from Stefan Lofven.
He resigned as prime minister a week later, after seven years in power, in order to give her time to prepare for the September elections.
