Now the Conservatives are demanding a formal inquiry into the matter, just months before the government of Gordon Brown must call a general election.
The Government has always denied that social engineering played a part in its migration policy.
However, the paper, which was written in 2000 at a time when immigration began to increase dramatically, said controls were contrary to its policy objectives and could lead to “social exclusion”.
Last night, the Conservatives demanded an independent inquiry into the issue. It was alleged that the document showed that Labour had overseen a deliberate open-door policy on immigration to boost multi-culturalism.
Voting trends indicate that migrants and their descendants are much more likely to vote Labour.
The irony is that if Labour were using mass immigration to cement a new and loyal voting base, the governing party seems to have all but alienated its traditional white working class voters. In some districts, this has created fertile ground for the emergence of the BNP. Politics, like nature, abhors a vacuum.
