"Who are the bombers? They are going to be single males traveling on their own... If you are traveling with a family of kids, on you go; the chances you are going to blow them all up is zero," he said.
"You can't say stuff, because it's racism, but it will generally be males of a Muslim persuasion. Thirty years ago it was the Irish," he said continued. "If that is where the threat is coming from, deal with the threat."
The Muslim Council of Britain was quick to condemn the comments as "racist and discriminatory".
