Of course what UKIP is doing is playing on some people's dislike of already settled immigrants. But most immigrants are just workers who've moved here in search of work and finding it. In fact many of what the BNP, UKIP's cruder rival for the anti-immigrant vote, call the "indigenous" population will be the descendants of one-time immigrants. Everybody with an Irish name for instance, and that's a lot.
The Socialist attitude is that all workers, irrespective of their first language or where they were born, share a common interest in uniting, as long as capitalism lasts, to get the best terms they can for the sale of their working skills and, more importantly, in getting rid of capitalism and replacing it with a world community without frontiers based on the common ownership and democratic control of the Earth's resources so that these can be usd for the benefit of the whole world population.
It's not clear whether UKIP will be standing in Vauxhall -- the poster was in neighbouring Battersea. Just checked who it is and it says:
From a military family, Christopher was brought up in this country and the middle east.Hold on a minute. Middle East? So it's alright from his family to have settled there in connection with their work but not for families from other parts of the world to settle here.
