Mixed system
Ukraine has a mixed voting system. Under the current election law, 225 of the 450 seats will be allocated on the basis of proportional representation among the parties that manage to clear the 5% threshold. Candidates compete for the other 225 seats in first-past-the-post races in single-mandate constituencies. Those running can represent parties or stand independently. However, the Central Electoral Commisison has said that voting will not take place in 15 constituencies of eastern Ukraine and so the new parliament will have 423 MPs and not 450.
