Ukraine Election: Yulia Tymoshenko is one of the frontrunners

Ukraine will elect a president on Sunday. In what's seen as a three-way contest, Volodymyr Zelenskiy, a television comedian is expected to win the first round. But it may go to a run-off, and the other two main candidates are longstanding political rivals: the current President Petro Poroshenko, and former Prime Minister Yulia Tymoshenko.
