A group of around 200 protesters, most of them aged in their mid-20s, gathered outside the venue of the AfD's post-election Alexanderplatz, writes James Rothwell in Berlin.

Bemused AfD supporters looked on from the balcony of Club Trafic as protesters chanted "Nazis rays (Nazis out)" "Nazi pigs" and in English "Refugees are welcome here."

A police cordon of police officers surrounded the entire venue.

"This is it, the Nazis are back in parliament," a protester who gave his name as Ben told the Telegraph.

"I wasn't shocked when I saw the exit poll because we suspected this was coming.

"We are here to protest the rise of extreme politics, which has always been here but is now going back into the mainstream.

"People think the AfD wants to support the people but they are wrong, they pretend they support workers but they are led by neo-liberal capitalist economic professors. They have fooled the voters in the provinces into thinking they are standing up for them.

"The most extreme people in the party are actually the younger members, they are the activists who are using fear to spread hatred and racism."

A neurology student who gave her name as Johnston added: "Berlin is kind of a bubble of left wing views so people here don't always realise what is going on. That's why it's important we came to the protest.

"People are clearly angry and they feel negkected but the far right is not the solution to that. It has exploited people's fears about the migration problem, especially in the provinces.

" Until now I had hoped this wasn't going to happen but we are here and the extreme right is back."

"To be honest I am disappointed by the turnout," said a co-organiser of the protest.

"I was hoping a thousand people with coukd come but right now its maybe 200."
