Never believe Putin is unstoppable – after Navalny, this is how a new global opposition can bring him down | Masha Alekhina

Westerners are financing the same bloodshed they condemn. The time for the world's deep concern' is over - Russia and Ukraine need action

• Masha Alekhina is a Pussy Riot activist

Alexei Navalny was one of the first to come out in support of Pussy Riot after our arrest in 2012. His birthday congratulations telegram arrived at my prison faster than anyone else's. Laughing at enemies, loving life, he was full of vitality. On 16 February, he was killed in the Polar Wolf penal colony north of the Arctic Circle.

The loudest, clearest and brightest voice against Vladimir Putin's regime has been murdered, despicably, out of sight. Before his murder, he was tortured for three years; a third of this time was spent in solitary confinement without proper food and clothing. Navalny was killed a month before the so-called elections". Putin killed him, just as he killed Boris Nemtsov. He killed both out of envy - envy for the people's love, which he, a petty tyrant from the KGB, will never enjoy.
