A vocal critic of Russian President Vladimir Putin has shared a picture from his hospital bed as he recovers from being poisoned with novichok.
Alexei Navalny said he has managed to breathe for an entire day without requiring medical assistance, and told his Instagram followers: “I miss you all.”
On Monday, two independent laboratories in Sweden and France confirmed German findings that the opposition leader had been poisoned with the nerve agent.
Accompanying the photograph, where he is surrounded by his family, Mr Navalny wrote: “Hi, this is Navalny. I miss you 😍. I still can hardly do anything myself, but yesterday I was able to breathe on my own all day long.
“I did not use any outside help, not even the simplest valve in my throat. I liked it very much. An amazing, underestimated by many process. I recommend it.”
Mr Navalny, 44, is being treated in Berlin and was put in an induced coma after falling ill on 20 August during a flight in Russia.
It has been claimed the novichok was put in his tea at the airport.
Russia has denied any involvement and says it has so far seen no evidence that Mr Navalny was poisoned.
Samples from Mr Navalny have also been sent to the Organisation for the Prevention of Chemical Weapons (OPCW) in The Hague for tests.
Novichok is the same substance used to poison former spy Sergei Skripal and his daughter in Salisbury in 2018 – an attack that Russia denies orchestrating.
German Chancellor Angela Merkel has said the use of novichok showed the “dangerous” attack on Mr Navalny was attempted murder and an aim was to silence him.
