Former UKIP leader Nigel Farage | Carl Court/Getty Images Nigel Farage to campaign for far-right AfD Brexiteer will appear alongside Beatrix von Storch in Berlin.

Nigel Farage will be in Berlin on Friday at a campaign event for the far-right Alternative for Germany, alongside a politician who once said police should be able to shoot at refugees.

Former UKIP leader Farage is described as "Mr. Brexit" in a poster for the event with Beatrix von Storch, two weeks ahead of the September 24 German election. The exact location of the event has not been disclosed for safety reasons, von Storch said.

On her Facebook page, von Storch said Farage will be talking about the development of the European Union, Brexit and "how to make the impossible possible."

She also called him her "most appreciated colleague" — both are members of the Europe of Freedom and Direct Democracy group in the European Parliament.

Von Storch is a controversial figure who last year said police should be allowed to use weapons against women and children who enter Germany illegally. She later tried to water down her comments, writing: “The use of firearms against children is not permitted.” However, she added that “women are a different matter.”
