Ukrainian confectionery tycoon Petro Poroshenko has claimed outright victory in the country's presidential election.

Mr Poroshenko, who is known as the "chocolate king", won more than 55% of the vote in the first round, exit polls suggest.

Pro-Russian separatists severely disrupted voting in some areas.
