As a result, the Social Democratic leader has announced her resignation, which will be officially presented on Thursday.
The bloc formed by three right-wing parties and the far-right Sweden Democrats (SD) party has “a small majority, but still a majority”, she said during a press conference.
“I will therefore ask tomorrow (Thursday) to be relieved of my duties as Prime Minister and the responsibility for the rest will be entrusted to the President of Parliament,” she added.
According to almost final results covering more than 99% of the polling stations, the right/extreme right bloc led by the conservative Ulf Kristersson will obtain 176 seats, against 173 for the left bloc led by Ms Andersson.
Sunday’s elections were so close that it was necessary to wait for a count of a few tens of thousands of missing votes on Wednesday to validate the complete results.
Only those in a few offices were still missing Wednesday evening around 7:45 p.m. local time (5:45 p.m. GMT).
