 "Alexei Navalny")
Russian opposition politician Alexei Navalny was detained on Monday en route to a political protest in Moscow, his wife wrote on his Twitter account, posting a photo of him getting into a police car.
"Hello. This is Yulia Navalnaya... Alexei has been detained in the stairwell," she wrote about 40 minutes before an anti-corruption rally called by the Kremlin critic was set to start in the city centre.
