Lyudmila Navalnaya, who has been trying to get his body since Saturday, appeared in a video outside the Arctic penal colony where Navalny died on Friday.
“For the fifth day, I have been unable to see him. They wouldn’t release his body to me. And they’re not even telling me where he is," a black-clad Navalnaya said in the video, with the barbed wire of Penal Colony No. 3 in Kharp, about 1,900 kilometers (1,200 miles) northeast of Moscow.
"I’m reaching out to you, Vladimir Putin. The resolution of this matter depends solely on you. Let me finally see my son. I demand that Alexei’s body is released immediately, so that I can bury him like a human being,” she said in the video, which was posted to social media by Navalny's team.
Russian authorities have said the cause of Navalny’s death is still unknown and refused to release his body for the next two weeks as the preliminary inquest continues, members of his team said.
They accused the government of stalling to try to hide evidence. On Monday, Navalny’s widow, Yulia, released a video accusing Putin of killing her husband and alleged the refusal to release his body was part of a cover-up.
“They are cowardly and meanly hiding his body, refusing to give it to his mother and lying miserably,” she said.
Lyudmila Navalnaya and her son's lawyers went to law enforcement agencies and the morgue where the body is believed to be held in the Arctic region, but were unable to get them to turn it over or say where it is.
Kremlin spokesman Dmitry Peskov rejected the allegations of a cover-up, telling reporters that “these are absolutely unfounded, insolent accusations about the head of the Russian state.”
Putin hasn't commented publicly on Navalny's death. On Monday, he signed a decree promoting a number of law enforcement and military officials, including Valery Boyarinev, the first deputy chief of the State Penitentiary Service. Boyarinev, who received the rank of colonel-general, has been accused by Navalny's team of personally ordering restrictions on the opposition leader.
Peskov denied there was any connection between Navalny's death and the new rank for Boyarinev.
