Russia's jailed opposition politician Alexei Navalny might have been exposed to an unidentified "toxic agent," his personal doctor said on Monday, while health officials insisted his condition was satisfactory.
"Some toxic agent may be the reason for Alexei Navalny's 'illness'," his physician Anastasia Vasilyeva said in a post on Facebook, adding that officials at Moscow's hospital No 64, which treated him, have behaved strangely.
On Sunday, President Vladimir Putin's top opponent was rushed from jail to hospital suffering an acute allergic reaction.
Vasilyeva said later Sunday the 43-year-old could have been exposed to an "unknown chemical substance", complaining she was not allowed to properly examine him.
A representative of the hospital told AFP on Monday Navalny was "in a satisfactory condition."
"They have decided against establishing the cause of generalised oedema and rash."
