Viktor Yushchenko

Viktor Andriyovych Yushchenko (Ukrainian: Ві́ктор Андрі́йович Ю́щенко; born February 23, 1954) is a Ukrainian politician who was the third President of Ukraine from 23 January 2005 to 25 February 2010.

As an informal leader of the Ukrainian opposition coalition, he was one of the two main candidates in the 2004 Ukrainian presidential election. Yushchenko won the presidency through a repeat runoff election between him and Prime Minister Viktor Yanukovych. The Ukrainian Supreme Court called for the runoff election to be repeated because of widespread electoral fraud in favor of Viktor Yanukovych in the original vote. Yushchenko won in the revote (52% to 44%). Public protests prompted by the electoral fraud played a major role in that presidential election and led to Ukraine's Orange Revolution.

Following an assassination attempt in late 2004 during his election campaign, Yushchenko was confirmed to have ingested hazardous amounts of TCDD, the most potent dioxin and a contaminant in Agent Orange. He suffered disfigurement as a result of the poisoning, but has been slowly recovering.
