Ukraine's ruling party was set to win the most votes in legislative elections on October 28, 2012 but faced a strong challenge from the party of ex-premier Yulia Tymoshenko whose jailing sparked Western concerns of foul play. The biggest surprise package is the ultra-nationalist Svoboda (Freedom) party which according to critics is a far-right force with a track record of racist rhetoric. Projected to win 12.3 percent of the vote, it appears to have done well on frustration with the existing political heavyweights. AFP PHOTO/ GENIA SAVILOV
