I'm sure the medics have:
1. Unions,
2. Racial discrimination/human rights laws,
3. Professional cabals
which can be utilised to deflect, to a convenient slop barrel, away such racist demands.
I suspect young, newly educated and expensively trained by UK taxpayers, are not required to "buy their way into the NHS with a premium".
But "Johnny Foreigner", presumably with the correct visa/permission to work ..., educated and trained by foreign taxpayers/self funded, bringing much needed capacity to the NHS, will be required too.
Is there not a pool of impoverished medics, from the newly admitted to the EU, to tap?
