Some 120,000 to join Thursday rallies in Moscow
Some 10,000 police officers will be deployed to Moscow streets during the demonstrations, Moscow police said in a statement.
Putin supporters will march along the Frunzenskaya Embankment in central Moscow before gathering at Moscow's Luzhniki Arena at 1 pm local time (09:00 GMT). The demonstration, which was authorized for 100,000 people, is expected to last until 2.30 pm (10:30 GMT).
Putin's press secretary Dmitry Peskov has not ruled out that the prime minister may address his supporters with a speech during the demonstration.
Members of Putin's United Russia party are also expected to attend the rally, which was jointly organized by Putin's election staff and his All-Russia People's Front movement.
Another rally, organized by TV anchor Sergei Kurginyan, will take place on Thursday at the All-Russia Exhibition Centre in north-eastern Moscow. Its participants will protest against what they call "Orange threat" facing Russia, referring to the 2004 Orange Revolution in Ukraine, one of the so-called color uprisings that rocked former Soviet republics in the 2000s.
Kurginyan followers believe that the leaders of recent "For Fair Elections" protests in Russia are foreign-backed revolutionaries, who, according to Kurginyan, "don't need honest elections any longer and will not recognize the results of the March 4 presidential polls in any case."
Only 7,000 people were allowed to attend the rally, while some 13,500 have signed up on social networks to join it.
