The acutely ill Russian opposition leader Alexei Navalny has arrived in Germany from Siberia for treatment.

He is in 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.

On Saturday morning, Mr Navalny’s medical evacuation flight – paid for by the German NGO Cinema for Peace – landed at Tegel airport in Berlin. He is being treated at the Charité hospital in the German capital.

The founder of the Cinema for Peace Foundation, activist and filmmaker Jaka Bizilj, told German newspaper Bild that Mr Navalny’s condition had remained “stable” throughout the flight and after landing.

Medical staff treating Mr Navalny at the hospital in Omsk said before his flight that his life was not in immediate danger.

Mr Navalny’s spokeswoman, Kira Yarmysh, earlier tweeted: “Massive thanks to everyone for their support. The struggle for Alexei’s life and health is just beginning.”

Ms Yarmysh said it was a pity that doctors had taken so long to approve his flight as the plane and the right documents had been ready since Friday morning.
