Sunday’s election could lead to a battle between far-right’s George Simion and Marcel Ciolacu of Social Democrats

Romanians are casting ballots on Sunday in the first round of a presidential election that could pit a far-right nationalist against the incumbent leftist prime minister in the runoff.

Thirteen candidates are vying for the presidency in the EU and Nato member country and the vote is expected to go to a second round on 8 December. Polls opened at 7am local time (05.00 GMT) and will close at 9pm. Romanians abroad have been able to vote since Friday.
