KIEV (Reuters) - The two remaining candidates in Ukraine's presidential race underwent televised drug and alcohol tests on Friday, capping a week in which they traded jibes in tit-for-tat social media videos and goaded each other to agree to a live policy debate.

President Petro Poroshenko is facing Volodymyr Zelenskiy, a comedian with no political experience who plays a fictional president in a TV series, in a run-off on April 21 after neither obtained a majority of votes in the first round last Sunday.
