… because that would be fascism! Instead, we’re likely to get the NHS checking people’s passports and utility bills (for proof of address) before they can get medical treatment.
As I’ve commented before, the British seem obsessed with not having national ID cards — when they came into power one of the first things the Conservatives did was to cancel a Labour programme that had been in the works for about five years to provide ID cards — because carrying an ID card is inimical to Anglo-Saxon freedom. They don’t object to round-the-clock video surveillance, police stopping foreign-looking people on the Tube to ask for proof of right to be in the country, or now checking nationality documents at the hospital.
They just object to providing people with the documents they need to meet the authorities’ demand (given that one in six Britons has no passport, and they cost about £80). Instead, they leave it up to easily falsifiable electric bills to attest their address.
