http://www.bbc.co.uk/news/uk-16643677Work-related benefits were being claimed last year by more than 370,000 migrants who originally came to the UK to work, study or visit, the first research of its kind has shown.
The government matched benefit, border control and tax records from 2011.
A look at a sample of 9,000 claimants of certain nationalities found 2% were illegally claiming benefits.
Ministers said it was unacceptable for people to claim benefits in the UK without having worked or paid tax here.
BBC correspondent Naomi Grimley says the government admits it found only a tiny number of cases where migrants were claiming illegally, but the research is likely to prompt a wider debate about whether the welfare system has become too generous and attracted so-called "benefit tourists".
Before the coalition government came to power the nationality of benefit claimants was not recorded.
Anyone surprised by this? And no surprise that Labour deliberately didn't record the nationality of those claiming benefits, of course they didn't want to let the cat out of the bag - it might puncture the myth that we benefit economically from mass immigration which of course we do not. It enriches a few (businesses and corporations) at the expense of the rest of us.
