The anti-immigrant Alternative for Germany (AfD) party on Sunday chose a tough-talking former member of Chancellor Angela Merkel's conservatives and an economist to lead its campaign for a September election in a line-up likely to drag the group further right.
The party had stolen voters from Merkel during the migrant crisis but now looks less of a threat on 8-10% in polls after bleeding a third of its support as the refugee influx has slowed, infighting damages its image and a controversy about how to deal with Germany's Nazi past deters voters.
A majority of AfD delegates at a congress in the western city of Cologne backed 76-year-old publicist Alexander Gauland and Alice Weidel, a 38-year-old former investment banker, as candidates fronting the party's bid to win seats in the national parliament for the first time in a September 24 election.
The vote followed a surprise announcement on Wednesday by co-leader Frauke Petry, the party's public face, that she would not lead the AfD's election campaign. This could boost mainstream parties and lessen the threat the AfD poses to Merkel's bid for a fourth term.
Gero Neugebauer, a Berlin-based political expert, said the choice of candidates would not boost the party's prospects because most AfD members did not vote based on the people representing it as they have no chance of power. But the duo chosen signalled the party was shifting further right, he said.
"Both people represent the AfD as a party that wants to present itself as middle-class, conservative and economically liberal but which is in essence a party that is moving further to the right," Neugebauer said.
Gauland is widely seen as a supporter of senior AfD member Bjoern Hoecke, who caused outrage in January by calling Berlin's Holocaust Memorial a "monument of shame" and demanding a "180 degree turnaround" in Germany's attempts to atone for Nazi crimes.
A lawyer who grew up in the former communist East before fleeing to West Germany to go to university, Gauland once compared refugees coming to Germany with barbarians who brought down the Roman Empire.
Sporting his trademark tweed jacket in Cologne, Gauland said the AfD wanted "to keep the country we inherited from our mothers and fathers" and preserve German identity, adding: "We're proud to be Germans."
He said Merkel, whom the AfD attacks for allowing in more than a million migrants over the last two years, must be overthrown so Germans can get their country back, drawing applause from delegates who shouted: "Merkel needs to go!"
Weidel, a little-known figure in the AfD and seen as more moderate, is in favour of expelling Hoecke.
A critic of the euro who has worked in China, Weidel has sought to establish herself as an economic expert. She recently stepped up her criticism of Islam.
Speaking in Cologne, she said the AfD would get into regional parliaments in Schleswig-Holstein and North Rhine-Westphalia in state elections in May. "Then we'll rock Germany" and become the only "real opposition party" in the lower house after September's election, she said.
"Political correctness belongs to the scrap heap of history," she added.
The AfD, which has lurched to the right since being founded as an anti-euro party in 2013, is treated as a pariah by established political groups, which refuse to work with it.
Delegates refused on Saturday to discuss Petry's motion to shift the party into the "mainstream" and be prepared to join coalitions.
Petry told Reuters the AfD should have decided at the congress on its future strategy and drawn red lines, adding the AfD could learn from France's Marine Le Pen as her National Front had seen election results improve since doing so.
