The research, conducted by pollsters Norstat on behalf of the Institute for the Study of Societal Issues (MTÜ Ühiskonnauuringute Instituut) gave 31 percent of support among respondents to the opposition Reform Party, 24.8 percent to the major coalition party, Center, and 17.4 percent to the Conservative People's Party of Estonia (EKRE), also in office. A week earlier these figures had stood at 31.2 percent, 25 percent and 16.6 percent respectively.

These top three parties are followed by the opposition Social Democratic Party (SDE) on 8.5 percent, non-parliamentary Estonia 200 (7.9 percent) and coalition party Isamaa on 5.3 percent – again practically the same as last week, where the figures were 8.1 percent, 7.5 percent and 5.5 percent.

Again, Isamaa is only slightly above the 5 percent threshold required for Riigikogu seats under Estonia's d'Hondt system of proportional representation.

The three coalition parties together received 47.5 percent support, the two opposition parties, 39.5 percent.

A total of 4,003 Estonian citizens of voting age were polled and the results represent an aggregate from the period May 25 to June 22.

Norstat uses a combination of phone surveys and online questionnaires in an effort to ensure results are representative and says it weights the distribution of those polled on the basis of major socio-demographic characteristics. Norstat claims a margin of error of +/1 1.55 percent.

The Riigikogu itself broke up for summer, last week, and will return to work at the beginning of September.
