Reform's support did not change significantly over the past week, according to the research, conducted by pollsters Norstat on behalf of the Institute for the Study of Societal Issues (MTÜ Ühiskonnauuringute Instituut), and stands at 32.8 percent, though with support for the Center Party continuing to fall, now at 22.7 percent, the gap between the two parties – Reform, the largest party by Riigikogu seats but in opposition, and Center, second-largest by seats, and in office – has risen.

Support for the Conservative People's Party of Estonia (EKRE), in coalition with Center, continued its trend for a rise. Its support has increased by 2.3 percent over the past four weeks, Norstat says, and currently stands at 17.9 percent.

The "big three" are followed by the opposition Social Democratic Party on 8.5 percent of support in the latest ratings, non-parliamentary Estonia 200 (7.3 percent) and coalition party Isamaa, on 6.1 percent, a slight rise on previous weeks and the first time the party has exceeded 6.1 percent support since March.

A total of 46.7 percent of respondents supported the three coalition parties, compared with 41.3 percent support for the two opposition parties combined.

The survey covered the period July 14-August 10 and surveyed just over 4,000 Estonian citizens of voting age, Norstat says.

The next elections are in October 2021, for local government.
