Sweden faces a political impasse after its mainstream center-left and center-right blocs virtually tied in an election Sunday, while the far-right — which neither wants to deal with — made gains on a hard-line anti-immigration platform.

With nearly all votes counted Monday, the ruling center-left Social Democrats and Greens and their Left Party parliamentary ally had 40.6 percent of the vote, while the opposition center-right Alliance was on 40.3 percent.

That translates into a single-seat advantage in the 349-member Riksdag.
