BERLIN – A new nationalist party that is challenging the German government’s welcoming stance toward migrants has come third in municipal elections in a central region, one week before three more important regional votes, preliminary results showed Monday.

The three-year-old Alternative for Germany, or AfD, received 13.2 per cent of the votes in Sunday’s election for district councils in the state of Hesse, which includes the city of Frankfurt, an official tally showed.

Chancellor Angela Merkel’s conservative Christian Democratic Union received 28.2 per cent — 5.5 points down from its tally five years ago — while the centre-left Social Democrats got 28 per cent, a 3.5-point decline. Those two parties govern Germany together, There also were losses for the Greens — who are part of Hesse’s state government.

AfD has campaigned against migration over recent months, switching its focus after initially concentrating on opposition to bailouts of eurozone strugglers. Polls indicate that the party, which isn’t represented in the national parliament, will perform strongly in state elections in Baden-Wuerttemberg, Rhineland-Palatinate and Saxony-Anhalt next Sunday.

AfD received 10.3 per cent of the vote in Frankfurt, preliminary results showed. Final results are expected Thursday.

Party leader Frauke Petry celebrated what she called “phenomenal results.” She said in a statement that “the power of the established parties is crumbling.”

Merkel has accused AfD of fueling prejudices and offering no solutions. If the party wins 10 per cent or more of the vote in state elections and perhaps enters the national parliament, “a great deal will change for the worse in our society,” senior Social Democrat lawmaker Eva Hoegl told ARD television.

In the town of Buedingen, the one council in Hesse where AfD didn’t run candidates, the far-right National Democratic Party saw its share of the vote climb from 2 to 14 per cent. Officials are trying to ban the party.

Government spokeswoman Christiane Wirtz declined comment on that result.
