Chris Grayling has criticised Labours Phil Woolas for tip immigration plans

Labour "wanted social change", according to the new document

Labour encouraged mass immigration even though it knew that voters opposed it, Whitehall documents confirmed yesterday.

The Government said the public disagreed with immigration because of"racism" and ministers were told to try to alter public attitudes.

The thinking on immigration among Labour leaders was set downin 2000 in a document prepared for the Cabinet Office and the HomeOffice, but the key passages were suppressed before it was published.

The paper was finally disclosed under freedom of informationrules yesterday. It showed that ministers were advised that only theill-educated and those who had never met a migrant were opposed toimmigration.

They were also told that large-scale immigration would bringincreases in crime, but they concealed these concerns from the public.

Sections of the paper, which underpinned Labour policies thatadmitted between two and three million immigrants to Britain in lessthan a decade, have already been made public.

These have showed that Labour aimed to use immigration not only foreconomic reasons but also to change the social make-up of the country.

Fuller details released yesterday showed that Tony Blair"s ministersopened the doors to mass migration in knowledge of public oppositionand with the view that those who disagreed with them were racists.

Labour"s accusation that opponents of immigration are racisthas been dropped over the last two years as it has become clear thatformer Labour voters in party heartlands have been turning to the farright British National Party.

Ministers accept there is frustration at the loss of jobs to migrants and pressure on public services.

Yesterday Shadow Home Secretary Chris Grayling said: "TheGovernment has simply not been telling the truth about its policies onimmigration.

IMMIGRATION CONTROLS RELAX

New controls on immigration are to be relaxed to allow companies to bring in the workers they want.

Trade Minister Mervyn Davies said yesterday that Labour"spoints-based system, aimed at allowing only the highest skilled workersinto Britain, had had "teething problems".

He promised a "slightly differently tailored system" for employees brought into the country by multinational companies.

The points-based system, introduced last year, wasdesigned to ease concern over the impact of mass immigration oflow-skilled and low-paid workers, particularly in traditionalLabour-voting areas.

Success for the scheme is central to Labour"s pledge that the population will not be allowed to reach 70million.

"More and more evidence is now emerging to show that theydeliberately planned a big jump in immigration for their own politicalpurposes.

"Now they are trying to rewrite history to pretend those decisionsnever happened. Their conduct over all of this has been a completedisgrace."

Sir Andrew Green of the Migrationwatch pressure group said: "Thisreport confirms that ministers deliberately rode roughshod over publicopinion in adopting a policy of mass immigration.

"They concealed their real intentions in the hope that theywould benefit from the immigrant vote without losing their workingclass supporters. They are now paying the price."

But this morning Border and Immigration Minister Phil Woolas described the accusations as a "complete fabrication".

"It"s an old story. It"s based on a report that was ten years ago that wasn"t accepted by ministers at the time," he told Radio 4.

"For Migrationwatch, which is meant to be non-party political, to be playing this game, it"s all about the election. This is pure smear politics.

"It"s not true that there was a deliberate policy to have mass migration policy. Neither is it true that there was an attempt to open the doors.

"The acts of parliament throughout this period have been trying to control the global increase in migration and what the right are really worried about is that we"ve now done that with the figures coming down, the new points-based system, electronic borders."

Mr Woolas said the Conservatives could not "stand the idea" that Labour was on top of immigration.

David Cameron promised yesterday to limit immigration to tens of thousands a year, a level last seen in the 1990s.
