Can I thank the Minister for that response? I know that, at one time, it was being used by Natural Resources Wales to fill their gaps because of the cost of the merger. But, generally, I believe it's a very good thing, invest-to-save, and it is an opportunity to help the Welsh public sector and get as much as we can for what we spend. The question I've got is: how do we ensure that what works and is seen to work in one place is actually shared and followed up by other parts of the Welsh public sector, so that we can all benefit rather than just having some one-off successes instead of having successes across the whole sector?
