Don’t really care about party politics but I agree with Nigel Farage that ‘good immigration’ is good and ‘bad immigration’ is bad, pretty simple. Personally I do not think a polish supermarket or a mosque is an eyesore but I would do when there are 50 in a square mile. I read the NHS is at "breaking point" partly from pressures of immigration, so yes there are positive and negative effects.
Why from windrush onwards, was Jewish and polish immigration during WWII bad for Britain?
