If parliamentary elections were held tomorrow 33 percent of voters would back the Center Party, the survey showed. Support for the Reform Party and the Social Democratic Party (SDE) of the governing coalition was respectively 17 percent and 13 percent.
The rating of the Center Party was 6 percent higher than a month earlier. Juhan Kivirahk, sociologist at Turu-uuringute AS, said strong support for the party can probably be attributed to high public attention and the rivalry of long-time leader Edgar Savisaar and vice chair Kadri Simson for the party's top seat.
The Reform Party has lost 2 percent and the Social Democrats, 1 percent of support over the month.
The opposition Free Party and Estonian Conservative People's Party (EKRE) were supported by 11 percent and 9 percent of respondents, respectively, and the ruling coalition's third member Pro Patria and Res Publica Union (IRL), by 8 percent.
BNS will release the findings of TNS Emor's party popularity survey later in the day.
