Russian opposition leader Alexei Navalny died unexpectedly in a prison colony, with his body handed over to his mother in Salekhard.

Navalny's family and supporters accuse President Putin of orchestrating his death, while the Kremlin attributes it to natural causes.

His widow accuses Putin of 'torturing' the corpse, amid tensions over the handling of Navalny's body by Russian authorities.

The G7 has called on Russia to explain Navalny's death and to free those who are unjustly detained.

Russian investigators are conditioning the release of Navalny's body on his mother's agreement to a private burial, with no public funeral.

Lord David Cameron has sanctioned penal colony officials over human rights violations related to Navalny's detention.

Despite the Kremlin's denials, Navalny's widow is determined to persist in the fight against Putin's regime, honoring her husband's Christian-inspired activism.
