The highest scoring party in public support polls for most of the past few years, the ruling Reform Party, was surpassed by both the Social Democrats and the Center Party, according to the interim results of a TNS Emor poll commissioned by ERR.
The figures coincided with the resignation of Justice Minister Kristen Michal on Thursday, a day before the results were released.
The Reform Party's popularity descended to 21.4 percent at the end of November, while the Social Democrats picked up the lead with 30 percent. The other opposition party in Parliament, the Center Party, also exceeded Reform, with 24 percent.
Coalition partner IRL garnered 17.3 percent.
Emor conducts monthly polls in two sets of interviews of 1,000 respondents. Undecideds are not included in the party figures; the "can't say" answers amounted for 35 percent of all responses in November. There was no word on undecideds for this month's poll.
Since Postimees reported allegedly leaked figures on Friday, which were flawed, ERR decided to make an exception and publish the interim results that same evening. The second half of the poll is still ahead and the results will be published at the end of this week.
