Paris - In the second episode of AFP's five-part podcast series, we retrace Alexei Navalny’s steps in Siberia during the last moments of his ‘previous’ life, in the city of Tomsk where he was poisoned. A few hours later, he would feel what he described as ‘the kiss of death’.

‘It was terrifying. I started to feel that I couldn’t breathe anymore,’ recounts Vladimir Kara-Murza, another opposition figure who was also poisoned.

Who poisoned Navalny? Agnes Callamard, the former UN rapporteur on the poisoning, has little doubt about who was responsible.
