Klitschko, a political novice, has been highly critical of Yanukovich's leadership and is focusing his party's campaign on fighting corruption in the former Soviet republic of 46 million people.
Yanukovich's Party of the Regions and its allies are seeking to retain a majority in the 450-seat parliament to cement his leadership - and the interests of industrialists and big business who support him.
They are opposed by Klitschko's UDAR (Punch) and a combined bloc that includes the Batkivshchyna (Fatherland) party of imprisoned former Prime Minister Yulia Tymoshenko.
A survey published by the Democratic Initiatives Foundation on Monday gave UDAR 16% of the vote, behind the Regions with 23.3%. The United Opposition bloc, which includes Batkivshchyna, had 15.1%.
