I assume you are referring to Oswaldtwistle?
According to, dare I say it, Wikipedia, the district borough it resides in is 90.2% white and 8.4% S.Asian.....(and is a relatively high percentage when compared to some other regions.)
Of course if the 8.4% is congregated around a small specific area then it would certainly appear to be more predominantly Asian in that area/s......which leads to something I mentioned earlier regarding segregation and the problems of integration when mass immigration happens over the short term...something that Labours policies regarding immigration encouraged and has led to this lack of social cohesion in certain areas.
