To really hammer home the point here, that Conservative government, in an effort to make immigration numbers go down set immigration rules to impose a minimum income for jobs that could recruit outside the EU. That minimum was lower than the government austerity cut maximum pay for nurses. Result: can't hire non-EU nurses, shortage worsens. Waiting times increase.

Eventually, as this started to be more widely known the Conservative government "fixed" it. Not by paying nurses more, not by lowering the immigration income requirement to match what they pay skilled workers like nurses, but by specifically exempting nurses.
