The body of late Russian opposition leader Alexei Navalny has been handed to his mother, more than a week after he died in an Arctic prisoncolony, his spokesperson said on Saturday.

Navalny, President Vladimir Putins most vocal critic, died on February 16 in one of Russias toughest prisons in northern Siberia, where he was serving a 19-year sentence on charges widely seen as political retribution for his opposition.

Alexeis body was handed over to his mother. Many thanks to all those who demanded this with us, Navalny spokesperson Kira Yarmysh said on X, formerly known as Twitter.

For the past week, Russian authorities had refused to give Lyudmila Navalnaya custody of her sons body, after she travelled to the town of Salekhard in the Yamalo-Nenets region, the nearest settlement to the prison colony where Navalny died.

Navalnys team on Friday said they had filed a lawsuit to obtain the body, alleging that local investigators had threatened to bury him on the prison grounds if his mother did not agree to a secret funeral.

Yarmysh said plans for the funeral were still unclear.

Lyudmila Ivanovna is still in Salekhard. The funeral is still pending. We do not know if the authorities will interfere to carry it out as the family wants and as Alexei deserves, she said.

His team said previously the Kremlin was trying to block a public funeral, which could turn into a show of support for Navalnys movement and his opposition to Putin.

The Russian leader, who famously never said Navalnys name in public, has not commentedon the death of his most vocal critic. (AFP)
