Russian opposition figure Alexei Navalny is unconscious in hospital suffering from 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, adding that they suspected something had been mixed into his tea.

The Kremlin said that it wished Mr Navalny a "speedy recovery".

Mr Navalny, 44, has been a staunch critic of President Vladimir Putin.
