Forty-five percent of respondents in the May 26-27 and June 30-July 1 surveys said they had no confidence in lawmakers, who they said were largely inefficient and guided by narrow interests. While 41% said they trusted parliament, and 14% said they had no clear opinion.
Analysts said opinion polls have traditionally shown the parliament to be held in low esteem by Russians, who however do not often know who was elected from their constituency in the previous elections.
But some experts said that is a sign of a lack of confidence in the current parliament, dominated by the Kremlin-backed party, and low expectations from elections to the State Duma, the lower house of parliament, later this year, when members will be elected on a party list basis under a new law.
The president, the government and regional leaders enjoyed greater authority with Russians, with 64% of those surveyed saying they trusted them, 25% disagreeing and 11% unable to answer, according to VTsIOM.
Those surveyed had greater confidence in federal courts, 49%, whereas 31% of respondents said they did not trust them at all, and 20% were not able to express their attitude to the federal judiciary.
But district and city courts enjoyed less trust among respondents, the opinion center said, with 34% saying they had confidence in them, 45% saying they did not trust them at all, and 21% failing to express their attitude.
The surveys were conducted in 153 residential areas across Russia and involved 1,600 people. The margin of error did not exceed 3.4%.
