'The UK could be home to almost three-quarters of a million illegal immigrants, a study for London Mayor Boris Johnson suggests'
''Hard argument'
The study into the economic impact of an amnesty for illegal immigrants was carried out by the London School of Economics (LSE).
It estimates that, if a minimum of five years' residence in the UK were needed to qualify, 450,000 illegal immigrants could be granted amnesty.
Mr Johnson suggested an amnesty, which would offer some the right to work officially and eventually gain full citizenship, during the 2008 mayoral election. '
'Mr Johnson said it was a "hard political argument to win" but added: "If people are going to be here and we've chronically failed to kick them out it's morally right that they should contribute in their taxes to the rest of society."
'Chronic failure'
The government is now tightening up border controls, introducing the "e-borders" system which counts people in and out of the country.
But at current rates of deportation, using the LSE figure of 725,000, it would take 34 years and cost almost £9bn to clear the backlog of people who are currently in the UK illegally. '
So your saying nearly 750,000 people in the UK are surviving illegally, on nothing?
