Final letter to Alexei Navalny’s mother, Ludmila Navalnaya Russian investigators said about her son’s body, a family spokesman said today, Friday. Either his mother will agree within 3 hours to a secret funeral, with no public farewell, either her son will be buried in the penal colony in the arctic north of Russia, according to the Guardian website.

It is recalled that yesterday, Navalny’s mother who, as she said saw her son’s body, accused Russian investigators of “blackmailing” her for his funeral, saying they were trying to force her to have a private burial ceremony without anyone present. Meanwhile, Navalny’s team said the death certificate said the Russian opposition leader died of natural causes.

“Just give Lyudmila her son… unconditionally”said Dmitry Muratov, a journalist and Nobel Peace Prize winner, in a video posted on social media on Friday. More than 25 directors, artists, ballet stars, Nobel laureates and opponents of President Vladimir Putin have so far called for the release of Alexei Navalny’s body.

Navalnaya is said to refused the ultimatum and demands that the Russian authorities comply with the law.
