In just one hour on Wednesday evening, the mandate swung back and forth seven times between S and SD. Later in the evening, it also shifted from S to M, and later to V.
However, the red-green parties have consistently had the most seats overall, as it has moved between 176 and 173, and 175 and 174.
According to the Swedish Election Authority, the results are expected to be ready on Thursday. The city of Stockholm, which was late in starting its count, is expected to be ready this evening, reports SVT Nyheter.
However, Gothenburg will not be ready until Thursday, writes Göteborgs-Posten.
Corrected: In an earlier version, the wrong party was stated as having lost a mandate.
