Polls are open across Germany as the world’s third largest economy chooses a new leader to guide it through an era of febrile immigration debates and souring relations with Washington.

German citizens aged 18 and up can vote. At least 59.2 million people in the nation of 84 million are eligible, about 2.3 million of them for the first time. Polling stations are open from 8 a.m. to 6 p.m. local time. Four candidates are bidding to be Germany’s next leader in Sunday’s election.

Alternative for Germany appears to be headed for the strongest showing by a far-right party since World War II in Sunday’s national election and is fielding its first candidate to lead the country.
