Angela Merkel’s open-door immigration policy will lead to “civil war”, a senior member of the anti-mass migration Alternativ for Deutschland (AfD) party has said.

Hansjörg Müller said Germany could end up a “banana republic without any government” if high levels of immigration continue, warning that the country was “sliding towards anarchy”.

Mr Müller was asked by Russia Today for his thoughts on comments by Bavarian official Peter Dreier. Mr Dreier reportedly told German Chancellor Angela Merkel that his small town of Landshut would only take 1,800 migrants no matter how many arrive in Germany. The rest, he said, would be put on buses to Berlin.

Mr Müller said: “Usually he does not have the power, but we are not living in usual times.

“What we are now looking at is more and more Germany sliding towards anarchy. In this situation I think less and less is determined by law, more and more is determined by who acts.

“And the person who acts in fact has the power. So if he sends … refugees to Berlin, he sends them!”

He added that he hopes such threats will influence Mrs Merkel, but “knowing the psychological things that Merkel does all these days – I don’t believe in it, unfortunately.”

His comments come as the anti-Islamisation PEGIDA marches gather pace once more across the country.

The marches have proven a headache for the German authorities, showing the world that the country is not united behind Chancellor Angela Merkel’s open-door migration policy.

The marches started in Dresden but soon spread across the country, attracting tens of thousands of protesters. A crackdown followed, however, which cathedrals turning off their lights as the marchers walked passed, rallies banned under the pretence of anti-terror measures, and anti-PEGIDA material aimed at children.

AfD, which some have described the German version of UKIP, has been steadily rising in the polls as more migrants flood the country, much to the dismay of the country’s political and media establishment.

Last month, the German media were stunned when AfD official Björn Höcker unveiled the country’s flag on a talk show. Newspapers described Mr Höcker, who declared a “deep love for my country”, as “confused” and “crazed”.

The German Huffington Post went furthest, however, by comparing him to Hitler.
