The Home Secretary spoke with alacrity and clarity about the need to get the system right and, in the words of the shadow Home Secretary, to make sure that it is both fair and robust. To that end, it is important that people who choose to offer DNA should be encouraged to do so, if it speeds up their cases. All of us across this Chamber have dealt with cases in which there have been long delays and people have been left in almost endless limbo. The voluntary provision of DNA might be a helpful tool for dealing with that. I hope that the Home Secretary will look at that in the review that he is about to carry out.
