Geert Wilders' speech in Berlin on Saturday has drawn criticism from leading German politicians.
One of them, Green party leader Jürgen Trittin, said Geert Wilders' visit was an "affront to Berlin's cosmopolitan tradition", in a city that is home to hundreds of thousands of Muslims. "We must stop all attempts by smug right-wing populists and Islamophobic bigots to marginalise and vilify these fellow citizens," he said.
About 500 supporters attended the speech Freedom Party leader Geert Wilders gave in Berlin on Saturday.
In it he lashed out at Chancellor Angela Merkel: "Ms Merkel says that the Islamisation of Germany is inevitable...'More than before mosques will be an integral part of our cities'. My friends, we should not accept the unacceptable as inevitable…It is our duty as politicians to preserve our nations for our children."
He received a standing ovation for his remarks about Germany's war past: "Whatever happened in your country in the past, the present generation is not responsible for it."
Mr Wilders spoke at the invitation of Berlin Councilor René Stadtkewitz, who was thrown out of the Christian Democratic Union when he refused to cancel his invitation to Geert Wilders. Mr Stadtkewitz now intends to form a German version of the Freedom Party: Die Freiheit.
There were police officers among the audience to check if Wilders did not overstep the mark. A police spokesperson said: "We do not accept instigation to sedition."
More than 100 people took part in a protest against Mr Wilders' speech. The demonstration, which was organised by the Social Democrats and an association opposed to extreme-right politics, passed off peacefully. Some of the protesters brandished photos of the Dutch politician portraying him with a moustache similar to that worn by Adolf Hitler.
