It's complicated. Many non European immigrants seemed to be suggesting that immigration is too high, I guess many European immigrants never had a vote although I believe Commonwealth ones did. The areas you mention tend to have quite a lot of eastern european immigrants working in the hotel and leisure sectors but have fairly low numbers of Asian and Caribbean/Africans. Maybe people in these areas are concerned that their traditional cultures will be threatened by high immigration. Before anyone suggests otherwise I am just trying to answer the question not put forward a case for the reasons.
If you are saying it is fear of immigrants as opposed to the reality, as these areas actually have very low levels of immigration, then we finally agree on something!
