Dr Julian Lewis: Bearing the sub judice rule firmly in mind, what does the Prime Minister think of the principle of bringing a dying, decorated former soldier before the courts of Northern Ireland on charges based on no new evidence that are unlikely ever to lead to a conviction?

[The Prime Minister: I know this is an issue that my right hon. Friend and a number of other right hon. and hon. Friends have raised in terms of individual cases and the general principle. None of us wants to see elderly veterans being brought before the courts in the way that he has described, but we need to ensure that we have processes and systems in Northern Ireland that ​ensure that proper investigation is taking place. I understand that my colleagues feel that the state has let down people like the veteran that he cited, but the fact is that previous investigations have not been found to be lawful. That is why we are having to look at the process of investigation. I have said many times standing at this Dispatch Box that I want to ensure that we see the terrorists who cause the vast majority of deaths in Northern Ireland being properly brought to justice. That is what we are working on, and we will continue to work on a system that is fair.]
