Vitalii Volodymyrovych Klychko (Ukrainian: Віта́лій Володи́мирович Кличко́, born 19 July 1971) is a Ukrainian professional heavyweight boxer and the current WBC world heavyweight champion. He is also a leader of the political party Ukrainian Democratic Alliance for Reform and a member of the Ukrainian delegation to the Congress of the Council of Europe.
Klitschko also holds the distinction of being a three time world heavyweight champion, having previously held the WBO and WBC titles, and has never been knocked out or knocked down in any professional boxing bout.
His younger brother, Wladimir Klitschko, is the current IBF, WBO, IBO and Ring Magazine world heavyweight champion. Vitali is the first professional boxing world champion to hold a Ph.D. (in sports science).
Vitali Klitschko has recently announced that he intends to retire from professional heavyweight boxing at the end of 2010. As a result of his success he has been awarded Germany's highest award, the Federal Cross of Merit.
Klitschko won the super heavyweight championship at the first World Military Games in Italy in 1995. Vitali won the silver medal at the 1995 World Amateur Boxing Championships in Berlin, Germany, where he was defeated by Russia's Alexei Lezin in the final. In his autobiography, published in Germany in 2004, the boxer revealed that he tested positive for a banned substance (steroid) in 1996. He attributed the presence of the drug to treatment of a leg injury but was dismissed from the Ukranian boxing team and missed the Atlanta Olympics . His brother Wladimir moved up from heavyweight to super-heavyweight to take his place in the squad. His amateur record was 195-15 with 80 knockouts.
