This is from the House of Commons Library:
As they summarise it:
And Dido Harding wants to reduce dependence on 'foreigners' in the NHS.
Let me leave the ethics aside for a moment - and that is hard. Instead, just consider the feasibility. To train the replacement staff would cost Â£42 billion and many years. And she does not even provide a good reason for doing this. A good reason might be to discourage people leaving their home country's health system. But that would require support for that system, which she knows this country is not providing. So we are back to the ethics f this. And they stink. Her comment ts are inexcusable.
