I congratulate my hon. Friend on his new position and thank him for that answer. Does he believe that fewer prosecutions will be brought if the new offence of using grossly disproportionate force, which the Justice Secretary intends to introduce, is brought in?
Is there any systematic review examining the causes where prosecutions fail? Obviously it could be quite right that the court should find a person not guilty, but sometimes there is a failure to pursue the prosecution adequately, either because witnesses do not match up or the case is not properly put, so is there any systematic review of where prosecutions fail?
Yes, this is something in which the Director of Public Prosecutions takes a particular interest. As Law Officers, we are in the position of superintending the process, and we ask the sort of probing questions that the hon. Gentleman would wish us to ask.
