I thank David Melding for that. I do, of course, welcome the report of the Wales Audit Office. It was that report that highlighted the fact that there had been a reduction of £30 million in the cost of agency working staff in the last year in the NHS. And it was a balanced account of the achievements that have been made in Wales, but also pointing to new ways in which we can address skills shortages and costs in the future. In the second phase, which I've mentioned already, there will be further development of data collection, to provide standardised national data, to enable benchmarking and monitoring of improvement in spend, directly in response to some of the work that the auditor general summed up in his report.
