Ukraine's Central Election Commission says opposition leader Viktor Yanukovych has won the presidential election according to the final official count, AP reported. Sunday's announcement comes three days ahead of the Feb. 17 deadline for releasing the final official results of the vote. It deals a major blow to Prime Minister Yulia Tymoshenko's effort to overturn the results of the Feb. 7 vote before they are made official. A preliminary count of the votes showed Yanukovych defeating Tymoshenko by 3.5 percentage points after last Sunday's ballot. Tymoshenko said in a televised appeal to the public Saturday that the vote was rigged and vowed to challenge the results in court.
