Russian opposition figure Alexei Navalny is in unconscious condition in hospital with suspected poisoning, his spokeswoman has said.

The anti-corruption campaigner fell ill during a flight and the plane made an emergency landing in Omsk, Kira Yarmysh said on Twitter, as reported by BBC. She said they suspect Navalny was poisoned by something mixed in his tea. A hospital has confirmed his admission.

Navalny, 44, is a staunch critic of Russian President Vladimir Putin. In June he described a vote on constitutional reforms as a “coup” and a “violation of the constitution”. The reforms allow Russian President Putin to serve another two terms in office. Navalny was returning to Moscow from Tomsk.
