MOSCOW (Reuters) - Two people involved with Kremlin critic Alexei Navalny's recent political campaign said they have fled Russia as the jailed opposition leader launched a new bid to challenge his designation by prison authorities as an extremist.
Russian authorities have in recent months cracked down on groups affiliated with Navalny, 45, who is regarded by many at home and abroad as President Vladimir Putin's No. 1 foe. He is serving two-and-a-half years in prison for parole violations related to a fraud case he says was politically motivated.
