Roman Abramovich was poisoned with World War One chemical warfare agent Chloropicrin or a low dosage of Novichok, experts have claimed.
The claim came from investigative journalist Christo Grozev, who led research into the shocking incident and gathered specialists to explain what had happened. According to the WSJ, Abramovich and other peace negotiators suffered debilitating symptoms including temporary blindness on a mission in early March to Kyiv seeking an end to the war.
The Chelsea owner is said to have required hospital treatment in Istanbul after flying to Turkey from the talks in Ukraine. One theory for the alleged poisoning is that hardliners close to Vladimir Putin wanted to disrupt peace moves and prolong the war.
