Petro Poroshenko, a billionaire chocolate manufacturer, claimed the Ukrainian presidency with an emphatic election victory on Sunday, taking on a fraught mission to quell pro-Russian rebels and steer his fragile nation closer to the West.
A veteran survivor of Ukraine's feuding political class who threw his weight and money behind the revolt that brought down his Moscow-backed predecessor three months ago, the burly 48-year-old won 55 percent in exit polls on a first-round ballot marred by the reality that millions were unable to vote in the troubled eastern regions.
Results will not be announced until Monday but runner-up Yulia Tymoshenko, on 13 percent, made clear she would concede, sparing the country a tense three weeks until a runoff round.
Poroshenko, known as the "Chocolate King", has no time to lose to make good on pledges to end "war" with separatists in the Russian-speaking east, negotiate a stable new relationship with Moscow and rescue an economy sapped by months of chaos and 23 years of post-Soviet mismanagement and chronic corruption.
The size of his victory reflects in part Ukrainians rallying behind the front-runner in the hope of ending a political vacuum that Russian President Vladimir Putin has exploited to annex the Crimea peninsula and offer solidarity, and maybe more, to rebels in the east who want to break with Kiev and accept Russian rule.
"He has taken a heavy burden on his shoulders," said Larisa, a schoolteacher who was among crowds watching the results on Kiev's Independence Square, where pro-Western "EuroMaidan" protests ended in February in bloodshed that prompted President Viktor Yanukovich to flee to Russia. "I just want all of this to be over," she added. "I think that's what everybody wants."
In the eastern Donbass coalfield, where militants ensured polling stations were closed to some 10 percent of the national electorate, rebels scoffed at the "fascist junta" and announced a plan to "cleanse" their "people's republic" of "enemy troops". A minister in Kiev said in turn its forces would renew their "anti-terrorist operation" after a truce during the polling.
More than 20 people were killed in the region last week.
