It would be 'absurd' to use a prison in Great Britain in Texan prison, because the US state has a much more difficult legal system, his ministers warned.
Experts said it would be impossible to 'pick' elements of the Texan schedule, who traveled justice secretary Shabana Mahmood to America to see personally this week.
Texan prisons offer discounted penalties to well-behaved prisoners who participate in work or rehabilitation programs.
Disorders, with the exception of the most violent and sexual perpetrators, can earn 'good behavioral time' ten or 20 days, depending on their prison status, for every 30 days that they have the line. The project is credited to help the state to reduce its prison population from 152,661 during the launch in 2007 to 134,668 last September, and made the closure of 16 prisons possible.
But British experts said that Texas has his own balance, which means that prisoners who are confronted in prison for decades should more likely meet their only chance of freedom.
David Wilson, emeritus professor of criminology at Birmingham City University, said: 'The idea that one can import a single aspect of the criminal justice system in somewhere like Texas is nonsense. If similar levels of discounts in the British system were to be imposed, you would end with punishments that are essentially useless.
“Compared to this country, there is a completely different culture compared to crime and punishment in Texas that, for example, carry out the largest number of perpetrators in the US.”
Texas has carried out 593 executions since 1976, more than four and a half times that of Oklahoma, in second place. Prison conditions in Texas sometimes run to centuries for serious sex offenders and the murderers who avoid the death cell.

For comparison: the average time served by a convicted murderer here is 16 and a half years.
Punishments for other crimes are also much heavier in Texas.
For example, worsened attack carries five to 99 years in prison, compared to ten to 16 years in England and Wales. Steve Gillan, general secretary of the Association of the Prison Officers, said: 'I don't think it is credible to pick what appeals under the laws of another country or state.
'Texan conviction laws cannot be compared to those in England and Wales. It compares apples with pears. '
Mrs. Mahmood has a conviction assessment led by former Tory Justice Secretary David Likke, who can recommend a similar 'good behavior' schedule here when he produces his final report this spring.
