Someone said Leeds was overrun. No ?
There are approximately 1.7 million Muslims in the UK - this is out of a population in excess of 60 million. They can't overrun our cities. They simply haven't the numbers.
There cities which have Muslim "enclaves" like Birmingham and London, but these enclaves are small in comparison to the cities they inhabit. The media never shows you what it's like in the normal parts of the city, because that would just be too boring.
