A prominent Russian opposition activist has been jailed for the 14th time in a year.
Sergei Udaltsov was found guilty of resisting arrest outside Moscow’s central election committee building in October.
The leader of the Left Front has just finished a previous sentence in hospital after falling sick.
“He’s seriously ill,” said Udaltsov’s wife Anastasia.
“He didn’t eat or have anything to drink for the whole day. Even doctors said that he is now in a grave condition,” she told euronews.
A video of Udaltsov’s October arrest shows him arrive on a bike and talk to reporters. The activist did not appear to putting up any resistance when police took him away.
Meanwhile Russian Prime Minister Vladimir Putin faces more mass protests over alleged election fraud.
Former Finance Minister Alexei Kudrin has warned of a revolution unless officials take notice of public anger.
More than 100,000 people took part in a rally in Moscow on Saturday calling for a disputed election on December 4 to be held again.
