A Midland Labour backbencher has criticised Tony Blair's education policy for allowing "religious crackpots" to run schools.
Wolverhampton MP Ken Purchase (Lab Wolverhampton North East) condemned proposals to invite businesses and religious groups to build new schools.
In a Commons debate, he said this would lead to lower standards and harm Midland manufacturers, who needed a skilled workforce.
The collapse of MG Rover had highlighted the need to help manufacturers, he said.
The Emmanuel Schools Foundation operates three state schools in the north of England.
It is run by Christian businessman Sir Peter Vardy, and the schools teach both evolution and creationism, presenting them as competing theories.
Evangelical charity Christian Vision, run by Midland businessman Bob Edmiston, is also planning three schools in the West Midlands, starting with Grace Academy, in Solihull, which opens next year.
In the Queen's Speech on Tuesday, the Government promised a new Education Bill to welcome "new educational providers into the state system".
Mr Purchase said: "It seems to me fundamentally wrong that a business tycoon with £2 million to spare can become the master of the fate of perhaps thousands of youngsters, many with unsuspecting parents.
"Like many others in the House, I am frankly horrified that a religious crackpot - I do not apologise for the language - can take control of a secondary school and preach the discredited doctrine of creationism."
He told Ministers: "My concern is that the ideal of choice, so essential in the competitive world of retail consumerism, will be thrust into the world of education in an unreconstructed way, reducing what should be a carefully thought through decision that will affect the life chances of a child to the level of an impulse purchase."
Mr Purchase said he did not believe increasing diversity in the education system would necessarily benefit those who most needed help.
"As choice grows - whether paid for directly in fees to a private institution or through people moving house to get their children into a school near the top of the league tables - the number of schools judged as failing will increase," he said.
"The truth is that many of these failing schools are often working heroically against enormous and overwhelming odds.
"I do not believe that there is any serious evidence to suggest that more technology colleges, academies and grammar schools will somehow, by increasing competition for pupils, lift standards in disadvantaged areas where parents have neither the means nor the social skills to join an everfaster race to the so-called best schools."
