Russian most prominent opposition figure Alexei Navalny is unconscious after suffering from suspected poisoning and reportedly on a ventilator in the hospital’s intensive care unit.

In a series of tweets, Navalny’s press secretary Kira Yarmysh described how the opposition politician, who is also a staunch critic of the Kremlin, fell seriously ill around 30 minutes after takeoff from the city of Tomsk.

Ms Kira claimed the anti-corruption campaigner must have consumed something from tea he drank earlier in the morning.

In 2017, Mr Navalny also suffered a serious chemical burn after he was attacked with antiseptic dye.

Last year, his foundation was officially declared a “foreign agent”, enabling the government to subject it to more restrictions.
