(Reuters) – Russian opposition figure Alexei Navalny is unconscious 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.
“We assume that Alexei was poisoned with something mixed into the tea,” she alleged.
Mr Navalny is a staunch critic of President Vladimir Putin.
In June he described a vote on constitutional reforms as a “coup” and a “violation of the constitution”. The reforms allow Mr Putin to serve another two terms in office.
