As reported, a protest with a request to hold a political reform in Ukraine is being held Oct. 17 at Verkhovna Rada building in Kyiv. Organizers of the protest say the key demands are to change the system of election in Ukraine, including a shift to proportional election system with open candidates list, restriction of political advertising on TV, creation of anti-corruption court, and restriction of parliamentary immunity.
Former Odesa governor Mikheil Saakashvili said that if the MPs do not fulfill the protesters' demands on Oct. 17, some of them might stay at the Rada building for indefinite protest. SBU reported earlier it had prevented a possible provocation during Oct. 17 mass events in Kyiv.
