Presidential elections underway in Ukraine

Polls have opened in Ukraine as the country votes in the first round of presidential elections.

Current leader Petro Poroshenko is seeking re-election but the surprise front runner is comedian Volodymyr Zelenskiy.

Both candidates, along with former Prime Minister Yulia Tymoshenko, have expressed largely pro-European views during campaigning.

None of the pro-Russian candidates are seen as serious contenders.

If no candidate gets more than 50% on Sunday, the top two will fight it out in a second round on 21 April.

A total of 39 candidates are on the ballot paper, but only the three front-runners are considered to have any chance of victory.
