The Ukrainian parliamentary election took place on 26 March 2006. Election campaigning officially began on 7 July 2005. Between November 26 and 31 December 2005 party lists of candidates were formed. The election to the Ukrainian parliament, Verkhovna Rada, was held according to the Party-list proportional election system—that is, in a single nationwide electoral district with votes being allocated to the political parties or election blocs rather than to individual candidates. In the previous parliamentary elections half of parliamentary representatives (deputies) were elected on proportional basis, while the other half were elected in single-mandate constituencies.
