I am a serving Prison Officer of 15 years experience. I am currently on sick leave due to stress/anxiety caused by my work environment. I do not work in the private sector prisons, but in the public sector. I can honestly say that every one of the problems highlighted in your programme are in evidence within private prisons. In my opinion, every one of these problems can be traced back to chronic understaffing in order to save money so that the public sector can compete with the private sector.

I would like to say what an excellent programme Prisons Undercover was. I am the suicide prevention co-ordinator for a busy London prison. I just wish I had recorded the programme as the issues around self-harm and suicide could have been used as examples of the importance of completing and carrying out the correct checks.

I hope that your programme has a salutory effect on suicide watches throughout the UK because deaths in prison are a hugh tragedy for fellow prisoners, bereaved families and officers - but one hopes, as those dignified families did, that the lessons are systematically learned, and indeed subject to systematic research and inspection regarding their implementation.

Re: Prison Undercover. What a brilliant and accurate programme! I was a prison officer for four years in a private jail and can identify with all aspects of the problems shown. There are also a multitude of other knock-on problems that the programme did not have time to cover. I must make particular mention, though, of two points. Firstly, many inmates throughout the country will have watched that programme in their cells. This could have a huge impact for staff turning in for work tomorrow. Secondly, it should be noted that most officers don't give two hoots if some repeat criminal commits suicide. Society is a better place without them.

Having watched your programme on HMP Kilmarnock you may be interested in reading an article from the Prison Reform Trust which questions the role of private prisons. Go to www.prisonreformtrust.org.uk

I am glad that Premier is at last under scrutiny. My husband was in HMP Uttoxeter where he witnessed riots and was attacked. When he arrived his cell had been smashed up and smeared with excrement. My husband was eventually "ghosted out for his own protection. He was in fear of his life because of prison negligence.

Prison staff are still trying to do what we know should be done.The management don't want to help us. Needless to say, I don't work in prisons anymore!

I would have thought it would have been of more benefit to society to use the BBC's resources to filter drug rings looking for the pushers than undercover work in Prisons. Drugs affect our childreen who are innocent - perhaps the work is too dangerous and you have taken the soft option.
