To the layman, to someone like, say, Vladimir Putin, Novichok is famously untraceable, being lethal in tiny amounts, clear and smelling of nothing. T… - John Sweeney

In the flesh Vladimir Putin is nattily-dressed, very short and a dead ringer for an Auton, the ultra-creepy monsters in Doctor Who that morph into wheelie-bins and gobble you up and spit you out as plastic. His cosmetic surgery is not a great advert for Botox but if you get to be the master of the Kremlin no one's going to tell you your skin-job sucks.

Intriguingly, reporters from Novaya Gazeta were able to track down an unidentified prisoner in the Polar Wolf colony who told them that a 'strange commotion' had erupted in the prison on the evening of 15 February, before the official time of death. The secret prisoner said that the guards had accelerated their evening checks of the prisoners and strengthened security. In the morning of the 16th there was a 'total shakedown' of the prison, with guards confiscating mobile phones and other items from prisoners. Soon after, a committee from the central office of the Federal Penitentiary Service arrived, the prisoner said. Word spread throughout the prison that Navalny was dead at 10am Yamal time, 8am Moscow time, 0500 GMT, more than four hours before the official time of death.

He [Prigozhin] became the Kremlin's court jester, but beside the jokes he was, in essence, the psychopath's psychopath, Putin's personal cook and personal sadist, a killer, torturer and hot-dog salesman turned multi-billionaire, troll farm boss and mercenary warlord.
