The Guardian view on Sweden’s election result: an opportunity that progressive parties must not squander | Editorial

After a desperately tight race, voters rejected the prospect of the far right in government. A potential centre-left coalition needs to seize the moment

European progressives searching for reasons to be cheerful have been finding them hard to come by this autumn. In Germany, the dramatic rise of the Alternative für Deutschland party is threatening the liberal values that underpin the identity of the federal republic. In France, polls continue to point to a likely Marine Le Pen victory in a presidential election, which is months away. Across mainland Europe, centre-left parties are failing to muster an adequate response to nativist movements that have colonised swathes of the working-class support that they once relied on.

In such an ominous political landscape, the outcome of a cliffhanger Swedish election provides a much‑needed source of optimism – albeit one that comes with heavy caveats. Prior to last Sunday’s poll, the outgoing prime minister, Ulf Kristersson, was explicit that if his rightwing alliance won the largest number of seats, he would invite members of the far-right Sweden Democrats party (SD) to become ministers in the next government.
