If a woman who came to the UK specifically to avail of free healthcare, and her triplets (that nobody was expecting) took up places in NICU that were then unavailable for the baby of a local woman, and that baby died, then you really have to be wearing blinkers to refuse to see a connection between the baby's death and health tourism.
The connection is pretty obvious.
Blithely waving it off as "inadequate provision" means, I take it, that you presume, that you think expensive neonatal care should be planned with the expectation that women will show up from abroad heavily pregnant and be treated for free? How much tax, exactly, do you want to pay?
Are you happy for the NHS to collapse under the weight of your pride in allowing it to be used by people who have no entitlement to it? You're fine with UK residents care being compromised so that people from around the world can dump their most expensive health problems on our doorstep?
