Sweden votes in its first female premier

Andersson, 54, won parliamentary approval on Wednesday after reaching a last-minute deal with the former communist Left Party, but her grip on power is tenuous because of the Nordic country's fragmented political landscape.

Her predecessor, Stefan Lofven, governed by performing a complex juggling act to secure support from both the Left and Centre parties in parliament, even though they are not part of the coalition government.

But the Centre Party is worried by the deal with the Left Party and has said it will not back Andersson's government in a vote on a finance bill proposed by three opposition parties that could take place as early as at 1500 GMT on Wednesday.

Andersson had been finance minister since 2014 but now faces the prospect of governing on spending priorities determined by the center-right.
