Swedes are voting in a general election on Sunday that promises to be very close and that could see the far-right take on a key role in shaping the next government.

If the polls are correct, neither of the two main political groups — the center-left bloc that includes the ruling Social Democrats; and the four-party center-right opposition known as the Alliance — will win a majority.

According to an amalgamation of opinion polls, the Social Democrats of Prime Minister Stefan Löfven will win 25 percent of the vote, with the Moderates on 17 percent. The big winners are likely to be the far-right Sweden Democrats, on course to win around 20 percent of the vote — up from around 13 percent at the last election.

But while striking a deal with the Sweden Democrats — who have made migration and law and order the key planks of their election campaign — would give either bloc a majority, both have ruled out working with a party that has its roots in the neo-Nazi movement. Löfven has called the Sweden Democrats “a neo-fascist single-issue party which respects neither people’s differences nor Sweden’s democratic institutions.”

Here are some highlights of POLITICO’s coverage of Sweden and the election:
