Russia’s most prominent opposition politician has been suffering from severe stomach cramps in jail, feared to be caused by poisoning.
Kira Yarmysh, Alexei Navalny's spokeswoman, tweeted that an ambulance was called last week to the maximum security IK-6 penal colony at Melekhovo, about 155 miles east of Moscow, where he is being held.
Ms Yarmysh wrote: "We do not rule out that all this time in prison he could have been poisoned with something to make his health deteriorate slowly but steadily."
