Reform has dropped to its lowest level of support since the election in March 2019 and Estonia 200 has risen to its highest, December's survey by pollster Turu-uuringute AS and commissioned by ERR shows.
Non-parliamentary party Estonia 200's level of support rose to 20 percent - overtaking EKRE - while the Reform Party's has fallen to 21 percent. In June, Reform's support was 33 percent.
Estonia's 200 support has grown strongly over the last two months, in October, support was 7 percent. The party received 4.4 percent of the vote in the 2019 election, narrowly missing the 5 percent threshold.
In December's poll, the Center Party had 25 percent of respondents support, which is usual for the Turu-uuringute AS ratings as support for the party fluctuates between 22 and 27 percent.
EKRE gathered 14 percent of respondents support, the lowest since the Riigikogu elections when the party gained 17.8 percent of the total votes.
The ratings of other parties have remained unchanged over the last month with the Social Democratic Party (SDE) on 9 percent and Isamaa on 5 percent. The other parties did not reach the 5 percent threshold.
