A lot of the papers like UKIPs anti-Europe stance because they'd benefit from coming out of Europe, UKIP leadership don't care about immigration any more than the Tories, they want out of Europe to curtail the workers rights, as Lord Freud proved (he really shouldn't have apologised just for actually saying what he believes, people always say they want politicians to be honest, well, thats what you get when a Tory is honest), they don't care about the worker, only the capitalists making the profit.
If we leave Europe, immigration won't be capped, but the Working Time Regulations will dispear and your paid holidays along with it, Health and Safety regulations meaning your employer has to look out for you at work will go, the Equalities Act that protects your rights not to be discriminated against will vanish.
