Navalny’s spokeswoman, Kira Yarmysh, tweeted that the plane had flown to Berlin. It departed early on Saturday morning, Russian time. She said the “struggle for Alexey’s life and health is just beginning”.
Alexei Navalny is being flown from Siberia to Germany for treatment.
He fell into a coma after drinking what his supporters suspect was poisoned tea; they accuse the authorities of trying to conceal a crime.
Doctors treating him in Omsk had insisted on Friday that he was too ill to be moved.
But they later said his condition was stable enough for the flight. His wife Yulia is travelling with him.
A medical evacuation flight, paid for by the German NGO Cinema for Peace, is taking Mr Navalny to Berlin, where he will be treated at the Charité hospital.
“Alexei’s plane has taken off for Berlin,” his spokeswoman Kira Yarmysh tweeted on Saturday morning. “Massive thanks to everyone for their support. The struggle for Alexei’s life and health is just beginning,”
Navalny’s wife had appealed directly to Vladimir Putin to allow the evacuation. A medical plane chartered by a German NGO has been waiting at Omsk airport since early Friday morning to take him to Berlin’s Charité hospital.
The plane carrying the Russian opposition activist Alexei Navalny has left Moscow for Germany so he can receive treatment for a suspected poisoning that has left him in a coma for 36 hours.
Navalny’s spokeswoman, Kira Yarmysh, tweened that the plane had flown to Berlin. It departed early on Saturday morning, Russian time. She said the “struggle for Alexey’s life and health is just beginning”.
