Caporegime
The NHS bursary was scrapped AFAIK (I'm getting old). The NHS doesn't have a role in funding Doctors' training at the undergraduate level. The NHS doesn't have any say in the number of UK doctors trained.
There's plenty of other things the NHS does badly but this isn't really their remit.
Exactly, it was scrapped. The NHS doesn't have a role because they haven't allowed for it so it is their problem. Where I currently work we found there was a shortage of skilled mechanical fitters - solution - we funded apprenticeships. In a few years we removed the shortage of mechanical fitters that we were facing. There's nothing to stop the NHS redirecting some funds towards doing something similar instead of paying through the nose for incompetent or overpriced agency staff recruited from overseas.
Short-term pain, long term gain.
