Novichok 'found on water bottle in Alexei Navalny's hotel room'

Development suggests Russian opposition leader poisoned in Tomsk, not at airport

Associates of Alexei Navalny have said traces of novichok were found on a bottle of water in his hotel room in Tomsk, suggesting he was poisoned while in the Siberian city, and not, as previously suspected, from a cup of tea he drank at the airport.

The Russian opposition leader fell ill on a flight from Tomsk to Moscow on 20 August. The plane made an emergency landing in Omsk, where he spent two days in a coma before being flown by a medical jet to Berlin. He remains in the Charite hospital in the German capital.
