I agree with my right hon. Friend. I restate the point that, as he and the House understand, it is not for politicians to make decisions on individual prosecutions, but it is important that we send the clearest guidance we can to Crown prosecutors about when prosecution should follow. It is important, too, that sentencers make full use of the sentencing guidelines in this respect. The sentencing guidelines are clear that where an offence is committed by a serving prisoner, the sentence that follows, if a conviction occurs, should be consecutive and not concurrent. It is important that prosecutors do their bit to make that clear too.
