Alexei Navalny's Health in Critical Condition After Suspected Poisoning in Prison

Alexei Navalny, Russia's most prominent opposition politician, is in a "critical" situation after experiencing severe stomach pain in jail, which could be the result of slow-acting poison, according to a close ally. Navalny is serving sentences totalling 11-and-a-half years on charges including fraud and contempt of court, which human rights groups say were made up to silence him. His allies believe he is being slowly poisoned with a slow-acting poison applied through food. Worries over Navalny's health have been rising in recent months, and his team now believes he is being gradually killed.
