Yes, there's quite a lot of information available about the relative cost of independent contractors or managed practices, but it's also about our ability to attract and retain people to work in those services, not just GPs, but other clinical staff as well. So, we do have a range of those practices that have come in to be managed by Betsi Cadwaladr, and they've all managed to maintain a service for the local public, but my ambition is to have a more stable model for local healthcare to be delivered. That's why we talk about clusters coming together; we think we're going to see more co-working between those different practices. Those may be formal mergers; they may be federations. But, actually, to have that stability, whether doctors choose to work as an employed doctor employed by other doctors, or whether they wish to become partners—and we ought to incentivise people to become partners in general practice—and then to make sure they have a proper multidisciplinary team, that is more and more what we are going to deliver in local healthcare. If the Member wants further detail, I'd be happy to discuss outside the Chamber in correspondence.
