This is where it says immigrants cost more than what they bring in. Research by the Centre for Policy Studies revealed low-skilled migrants are costing taxpayers "more than they contribute at every stage of their time in the UK". Analysis of an Office for Budget Responsibility report found that the amount they cost the state - through benefits, healthcare and pensions - dwarfs the amount they pay in tax. The Centre for Policy Studies warned that the Government must "rebalance our migration policy" towards high-skilled workers. And the Tories insisted new restrictions should be placed on migrants. Only foreign workers who have not claimed benefits or relied on social housing whilst living in the UK on work visas will be given the right to remain indefinitely.
