Alexei Navalny walks down stairs as recovery continues

Russian opposition leader describes clear path' to recovery and praises Berlin doctors

The Russian opposition leader Alexei Navalny has been pictured walking down stairs, five days after a Berlin hospital said he had been taken off a ventilator and could breathe independently.

Navalny, the leading opponent of the Russian president, Vladimir Putin, fell ill in Siberia last month and was airlifted to Berlin. Germany said laboratory tests in three countries determined he was poisoned with a novichok nerve agent, and western governments have demanded an explanation from Russia.
