We are definitely putting in more investment, and we need to put in more investment. That is why we are spending £40 million on additional improvements in the existing infrastructure, and that is why we will spend well over £1 billion on building new prisons, but the urgent problem we face will not be addressed overnight by new prisons. These prisons will take serious time to build, and the problem will have to be addressed on the landings and outside the cells by legislative measures such as the Bill tabled by the hon. Member for Rhondda, by body-worn cameras, by CCTV, by training and, above all, by management and support for staff.
