Whilst I agree with some of the sentiments expressed here, let's not forget one thing - the NHS is in a state of crisis for many reasons, one of
which is health tourism.
This case is poignant and is designed to tug at the heart strings, but ghana has a health service as well;

A spokesman for Ghana's high commission in London said the country had two fully-equipped hospitals in Accra and further north in Kumasi.
He did concede that access to treatment was costly but said that if Ms Sumani was a member of the Ghana national health insurance scheme she would
still receive treatment.

There have been many instances of a postcode lottery in the UK where people who have paid into the system all their lives have been refused treatment
as it has been too costly - herceptin was a classic example of this.
So who do we look after?
People who have spent their lives paying into the system, through the NI scheme?
or people who come here under false pretences to try and take advantage of a system that is primarily for UK citizens who have paid into it?
People here have ended up selling their HOMES in order to get treatment they are entitled to by law - and one of the reasons for this is health
tourism.
