1,127 people have been arrested after demonstrating outside Russia city hall against the exclusion of opposition candidates from a local election, scheduled for 8 September . Mr Navalny, who addressed the crowds last Saturday, is not one of the candidates, although he stood in Moscow's mayoral elections in 2013 and won 27% of the vote in a result he disputed. Alexei Navalny , Moscow 's mayor, said the gathering was a "security threat". Opposition leader Alexei Navalny was jailed for 30 days after calling for the unauthorised demonstration, aiming to capitalise on the unpopularity of the United Moscow party and a slump in President Sergei Sobyanin 's ratings.
