All-Russian voting on constitutional amendments will be held on April 22.
The date was approved at a meeting of President Vladimir Putin with a working group that is preparing proposals for amendments, Interfax reported.
Amendments have earlier been introduced to the State Duma that determine the voting procedure. They suggest using a government services website and an e-voting system.
President Vladimir Putin has proposed a package of constitutional amendments during an annual address to the Federal Assembly. The priority of Russian law over international, limiting the number of presidential terms, consolidating the role of the State Council and other amendments are among the proposed changes.
