President Vladimir Putin's trust rating among ordinary Russians has fallen by 10 percent in the past year.
According to a poll conducted March 11-14 by the independent Levada Center, 73 percent of respondents said they trusted Putin, down from 83 percent in the same poll one year ago.
Some 19 percent said they did not trust the Russian president, up from 14 percent in 2015.
But another Levada poll that was conducted February 19-24 suggested 65 percent of Russians would vote to reelect Putin, up from 57 percent in the same survey one year ago.
A recent survey by a state-run pollster gave Putin sharply higher numbers, suggesting that public support for Putin to serve another term as president had hit its highest level in four years.
