The Ukrainian parliamentary election of 2012 took place on 28 October 2012. Because of various reasons, including the "impossibility of announcing election results" various by-elections have taken place since. Hence, several constituencies have been left unrepresented at various times. The election campaign was limited to 90 days. Every citizen of Ukraine 18 years of age or older was able to vote in 33,540 polling stations in Ukraine and 116 foreign polling stations in 77 countries.
