Compared to the previous Kantar-Sifo survey from June, the Social Democrats have lost 0.8 percentage points while the Sweden Democrats have gained the same amount. The Green Party has increased by 1.2 percentage points to 6.3%, its highest level in the year according to Kantar-Sifo.

The Moderates stay at a stable level around 18% and show small changes over time.
Blocks and seats
The current survey from Kantar-Sifo does not report block summaries or seat distribution. Therefore, it is not possible to draw conclusions about government support based on this survey.
Method and uncertainty
Kantar-Sifo's surveys are based on voter samples and results are affected by statistical uncertainty, especially for smaller parties near the four percent threshold. Margins of error are not specified in this report, but tend to be largest for small parties, and changes close to the measurement uncertainty should be interpreted with caution.
