PS - the logical problem with suggestions to stop recruiting foreign nurses and train more "English" ones is that it takes between three and five years to qualify as a nurse: -

So there would be a three to five year period during which there would be far too few nurses.

Of course a government trying to do anything other than cut expenditure might decide to spend the money on the training while still recruiting, and reduce recruitment as qualification numbers rose, so that natural wastage in numbers would be filled by the new recruits.
