Most big French cities have areas which have become "no-go zones" which non-Muslims and even police cannot enter, Nigel Farage has said.
The Ukip leader said that Britain and European countries have suffered from "moral cowardice" and allowed "big ghettos" to develop.
He said: "It's happening right across Europe. We have got no-go zones in most of the big French cities. We've been turning a blind eye to preachers of hate that have been coming here from the Middle East and saying things for which the rest of us would be arrested.
