Yanukovych had vowed to challenge the results of the Dec. 26 court-ordered presidential revote, which showed his opponent, opposition leader Viktor Yushchenko, winning a solid victory, according to preliminary results.
 

Yanukovych filed volumes of complaints with the Central Election Commission, alleging mass fraud, but the commission dismissed his appeal last week.
 

International observers have said that they saw no evidence of the mass vote-rigging that marred the Nov. 21 round of voting, in which Yanukovych claimed victory.
