Last week, we had a meeting of the cross-party group on cancer, where we were looking at the diagnostic workforce in Wales, and the issue that David Rees has brought up came up strongly, about the lack of endoscopy nurses, with a vacancy rate of 11 per cent. And, with evidence given about nurses leaving to go to private companies, I wondered what more the Government could do to try to ensure that we do manage to keep these nurses, who are obviously vital if we're going to develop our screening programme in the way he's described.
