The polls are closed in Ukraine, and national exit polls are indicating a clear first-round victory for chocolate magnate Petro Poroshenko, reports the BBC. Poroshenko claimed a decisive 55.9% of the vote, while Yulia Tymoshenko won a distant second-place slot with only 12.9%, reports the AP, amid heavy turnout. The margin was 2 percentage points, so Poroshenko clearly avoided a runoff; Ukraine watchers hope Poroshenko's strong showing will unite a fractious nation. (More Petro Poroshenko stories.)
