UK - Record numbers of migrants living in Britain are not working, costing taxpayers an estimated £8 billion, a report warns today. Official figures show that 1,689,000 non-UK nationals are either unemployed or classed as economically inactive because they are not looking for a job. It covers people aged between 16 and 64 who were born overseas and have the right to live in the UK, but excludes students and asylum-seekers. Researchers at the Centre for Migration Control think-tank put the cost to taxpayers of record levels of migrant worklessness at as much as £8.5 billion a year. They calculate that the total amount of public money attributed to workless migrants – including health, education, transport and housing costs, as well as welfare – could be as high as £20.3 billion. Robert Bates, research director at the Centre for Migration Control, said last night: 'For all the talk of a fiscal 'black hole', the Government seem to be missing the glaringly obvious fact that mass migration is causing economic pandemonium.
