Well, Dirprwy Lywydd, I had an opportunity to discuss the report briefly with Lord Thomas, who is leading the commission on justice that has been established here in Wales, a former senior judge, and he offers us a direct line of insight into the thinking of sentencers in this area. Why rates have risen in the way they have in Wales is a complex matter. There is an increasingly punitive climate of opinion that some analysts point to. There are certainly changes to legislation. There were over 3,000 new offences put on the statute book in 10 years from 1997 to 2007. We in this Assembly have put fresh offences on the statute book in the work that we do. There are the impacts of sentencing guidelines and guideline judgments that have had the effect of increasing length of sentences, quite certainly, and there is the issue of, as some sentencers put it, a collapse in confidence in the probation service. I said in answer to Leanne Wood that we welcomed strengthening probation, building confidence, in the consultation with the Ministry of Justice last summer. We'll do what we can within that, but want to go further.
