The rest of the parties were below the 5 percent election threshold.
Compared with February, the rating of Reform moved up 1.4 percentage points and the rating of EKRE 0.9 percentage points. The rating of the Free Party did not change, whereas the rating of SDE declined one point, the rating of IRL 0.8 points and the rating of Center 0.1 points.

The rating of the three parties of the ruling coalition, or Reform, SDE and IRL, was 47.3 percent combined in March, 1.9 percentage points lower than in February.
The answers of the people who listed "no preference" as to party identification were eliminated from the outcome to make it as comparable as possible with the outcome of an election held during the survey period.
Kantar Emor interviewed 884 voting-age citizens of ages 18-74 in their homes and over the internet for the survey from March 3 to 13.
