  First came the Polish plumbers, overturning the natural order
by tackling U-bends in a more reliable and affordable way than
their established British rivals. Now there is another field in
which east Europeans are driving well-paid Brits out of work -
on the frontline in Iraq and Afghanistan.  The market in which
ex-military can earn six-figure sums as private security guards
overseas is drying up, with salaries in sharp decline and
contracts increasingly being offered to cheaper foreign
soldiers, the Guardian has learned.  The National Association of
Security Professionals (Nasp), an organisation for those working
in the private security industry, said former British soldiers
are being laid off by companies in Iraq who are turning to east
Europeans instead. The number of Britons providing security in
Iraq has fallen from a peak of about 5,000 in 2004-05 to nearer
2,000 this year.  Mark Shurben-Browne, a director of Nasp, said
the market had reached saturation point, with companies
receiving 10-20 CVs a day
