Kremlin critic Navalny's condition still serious - spokeswoman

Kremlin critic Alexei Navalny, who is in a coma in a Berlin hospital after what his allies describe as a poisoning, continues to be in a serious condition, his spokeswoman Kira Yarmysh said on Thursday.

Navalny, 44, was airlifted to Germany on Saturday after collapsing during a flight from the Siberian city of Tomsk to Moscow. German doctors say there are indicators his illness is down to poisoning, a diagnosis Russian medics have contradicted.
