Moscow, Jun 29 (efe-epa).- More than three-quarters of Russian voters will back constitutional amendments that could see Vladimir Putin remain in the Kremlin until 2036, according to a poll published by the public opinion research center (VTsIOM) Monday.
The study said 76 percent of the electorate would vote in favor of a raft of constitutional changes in a referendum slated for Wednesday.
Some 23.6 of poll respondents said they would vote against.
Voting is taking place from 25 June to 1 July.
The Putin-backed amendments have already been passed by lawmakers and are being submitted to a so-called All-Russian vote.
The package of amendments, which must be passed or rejected in full, also proposes the inclusion of God in the constitution and the definition of marriage as a union between a man and a woman.
It would also ban the cessation of Russian territory and tighten the requirements for those seeking to run for president.
If passed, Putin would be able to remain in power until 2036, as the changes would abolish limits on consecutive presidential terms.
Opposition figures have described the move as a power grab and have called a boycott.
According to the current constitution, Putin would be unable to run in the next presidential elections in 2024, when his current term ends.
