“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 hospital said Mr Navalny was in a stable but serious condition. Mr Navalny, 44, 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” BBC News reported.
