Supporters of Russian opposition leader are expected to descend on Moscow city centre for an unauthorised protest against fraud

    Supporters of Russian opposition leader, Alexei Navalny, are expected to descend on Moscow city centre for an unauthorised protest against fraud.

   Navalny got permission to hold the rally at another location but said he had moved it after authorities tried to humiliate protesters. Small protests are being reported in cities in the Russian Far East.

   Meanwhile, the prosecutor's office has warned that police will take action against any unauthorised demonstrations.

   By calling crowds into the centre of Moscow, Alexei Navalny has set the stage for a confrontation.
