Of course, if "they" are sent "home", we will have no public transport, hardly any health service, no catering industry.....
And where is "home", anyway? Many members of ethnic minorities were BORN here....and so were their parents.
I take it the BNP is not aware of the fact that the reason "they" are here is that their countries were invaded and colonised by Europeans - not just the British - and stripped of raw materials to enrich the imperialist powers!
