Let us say ...
0 new nurses.
27k leave per year.
17k persuaded to stay (net loss 10k)
280k nurses in the NHS.
On this basis, you would have 0 nurses in the NHS by 2050 ...
Going from 280k to 310k FTE nurses is not a 50k increase despite claims you've prevented 20k leaving.
The chutzpah of this Gov is ... strong.
