Labour must give white working class people a fairer deal in order to stop the rise of the BNP, a Birmingham MP has told the Prime Minister.
Sion Simon (Lab Erdington) said residents in his constituency were not sharing in Britain's prosperity.
His comments, urging Mr Blair to consider the needs of the "white, working class" population, appeared to surprise some colleagues.
Mr Simon's constituency includes the Kingstanding ward, where BNP candidate Sharon Ebanks was controversially declared the winner in last month's local elections.
Labour successfully challenged the result after the returning officer said he made a mistake and declared the wrong result. The BNP says its candidate was the correct winner.
Speaking in the House of Commons, Mr Simon said: "Thanks to the Chancellor's economic miracle, unemployment, deliberately caused by the Tories, has been eradicated in much of this country.
"But in some constituencies, like mine, it remains a very, very serious problem at the heart of the white working class alienation which risks becoming a thematic undercurrent."
He added: "Will he set up a working group now, to deal with this scourge so that these people, our people, know that they have not been forgotten and the miracle has not left them behind."
