Technology and the sorts of things the noble Lord talks about are being developed all the time; he asked about technology not being lost through data loss, I think. This issue was human error in the coding. Much as I would like to say that human error does not exist, occasionally it does. This happened with the best technology systems in the world; how a system is coded will unfortunately predict what comes out the other end. I do not disagree with the noble Lord’s assertion at all.

My Lords, I recall being involved in a case in Southwark Crown Court where DNA convicted a man of rape 35 years after the offence. There was no other evidence. Statistically, there were would be only four people in the UK with the same DNA. What database exists for the recording of all DNA and other forensic scientific evidence where a crime is unsolved but the possibility of detection in the future remains? Will scenes of crime information of this sort be kept securely as part of the national law enforcement data programme, in the process of being developed by the Home Office, and if not, on what programme will it be kept?

I am slightly surprised by the noble Lord’s question because there has been quite strong feeling in your Lordships’ House, particularly from the Liberal Democrats, that DNA information should be automatically deleted after a certain period of time. The DNA records that were deleted required “no further action”. I totally understand the noble Lord’s point; I saw something about a conviction in Wales that went back years, and it was DNA that convicted that individual. On the holding of DNA, in most cases the data of unconvicted people has to be deleted.
