Yeltsin's successor, Vladimir Putin, opposed this.

In November 2018, Sergey Malinkovich, the central committee secretary of the Communists of Russia political party, called for the criminal prosecution of Vladimir Petrov for insulting religious believers by calling for Lenin's preserved body to be buried.[20][21] He said Petrov's proposal had violated the Criminal Code of Russia by insulting religious feelings and inciting hatred, and that he planned to "keep hounding" Petrov for his remarks.[20][21]
