"For decades our prison population has been growing but now one Conservative MP has come up with a solution - force inmates to learn to read and write.
He is suggesting judges impose literacy courses as part of prison sentences with offenders required to complete them before release.
It is just one of the ideas in a book Guy Opperman has written about how to tackle what he says is a crisis in our prison service.
In Doing Time, the MP also says the drug culture in our jails must be eliminated.
But he also suggests that churches, charities and communities ought to be given the opportunity to run what he calls Big Society prisons.
Many of the ideas - including those on literacy - come from Mr Opperman's personal experience as a criminal barrister. He became an MP in 2010.
He writes: "The sad reality in my experience is that very few clients were able to give you any meaningful written instructions.
"Too often my clients in prison simply could not read or write. It was very humbling."
The solution he believes is to make sure prisoners do leave jail with improved literacy and numeracy skills.
He says as few as one in five prisoners who need help actually seek it or receive it in prison.
So as well as imposing literacy courses as part of a prison sentence, he suggests that criminals be offered an early release if they complete them.
He said: "Many criminals are released early and we know that attaining this motivates those in jail to behave.
"If we allow judges to sentence criminals to literacy courses we can harness that motivation to give them the basic skills that will make them less likely to offend again."
The Conservative MP also calls for much stronger action to get drugs out of prisons.
He wants tougher screening of all those who enter or visit prison to try and keep drugs out.
He believes the government should trial a scheme where everyone entering a jail - from Home Secretary to relative - should be scanned or x-rayed, and if necessary, physically searched - something that does not happen at the moment.
He also wants every offender drug tested on admission and mandatory treatment programmes for those who are known users.
Mr Opperman also believes drug-free wings have to be created to make sure offenders who want to get clean can do.
And once again he says offenders should be offered an early release if they complete drug treatment programmes."
