Immigration figures underestimated

The number of immigrants arriving in Britain from the European Union was undercounted by half a million over a ten year period, a difference the size of Manchester, campaigners have warned.

In a letter to UK Statistics Authority chairman Sir Andrew Dilnot, Sir Andrew Green, of Migrationwatch UK said the "significance of the error underlines the scale of the task now facing the present government".

He added: "It is hard to think of a statistical series that is more sensitive in terms of public opinion, particularly at present."

A recent study suggested the immigration population in Boston, Lincolnshire, had risen by 500 per cent in 10 years.
